The mechanical adjustments of the ATN Thor sights allow for physical differences between individual operators using the system. The thermal scope functions include the Keypad, Output Connector, Eyepiece Diopter Adjustment Ring, Focusing Ring, Battery Module, Accessory Rail, and Weapon Mount.
The optical functions include an objective lens, thermal imaging detector, display and eyepiece. Infrared energy is emitted proportionally to the temperature of an object. The warmer the object, the more energy it emits. The infrared energy from the objects is focused by the optics, onto an infrared detector. The information from infrared detector is passed to electronics for image processing. The signal processing circuitry translates the infrared detector data into an image that can be viewed on the built-in OLED display. The image is observed through an eyepiece by operator.
The electronic circuit is powered by replaceable four 3V lithium batteries (CR123A). Power from the batteries is supplied to the componentsthrough the Power button.
The ATN Thor thermal imaging riflescope is a precision electron-optical instrument and must be handled carefully at all times. The ATN Thor thermal scope is designed to adjust for different users and corrects for most differences. The objective lens cover protects the scope from inadvertent exposure to extremely high levels of radiant flux. Never leave the scope with the objective lens cover off. To turn the unit on press the button labeled POWER. After a warm-up time of approximately 3 seconds, video of the thermal scene appears. During the warm-up time, a logo comes into view on the monocular display. Next the thermal image replaces the logo.
ATN Thor Focus System:
To focus the thermal scope you need to adjust the diopter first. The scope has an adjustable eyepiece with a range of +2 to -6 diopter. Simply turn the diopter clockwise until it stops. Then concentrate on any object and slowly turn the diopter back counter clockwise until the grain in the image is sharp. Then rotate the eyecup to accommodate use over the left or right eye. The ATN Thor models have ability to focus either long range or short. Focus the front lens to rotate it until the image and the grain are both sharp.The Thor features the all new ISM interactive symbology menu that enables you to easily navigate through the features and modes without having to go into a complex menu structure.
ATN Thor Polarity Adjustment:
POLARITY button switches the direct display mode into the reverse one, i.e. from hot-white/cold-black into hot-black/cold-white mode. If the polarity is white-hot, the image will be with hotter objects displayed as white, and the rest of the image displayed as black, and vice versa: with hotter objects displayed as black, if the polarity is black-hot. To select polarity go to ISM Main menu and push left arrow button to cycle between white hot and black hot polarities.
ATN Thor Brightness Adjustment:
Brightness allows you to dim or increase the brightness of the display. To cycle through the BRIGHTNESS steps go to ISM Main menu and push the down arrow button for brightness adjustment. Each short push of the buttons will cycle through the BRIGHTNESS modes, correspondingly, in stepwise way.

About Thermal Imaging:
Thermal Imaging Devices detect heat signatures and produce visible images of those signatures, called thermograms. Thermal imaging technology makes it possible to see without visible sources of illumination. Warm objects such as people and animals become readily visible against a cooler background and the user can see minute variances in temperature in the infrared spectrum.
History of Thermal Imaging Technology
The infrared spectrum was first discovered by Sir William Herschel as a form of radiation beyond red light. The first advanced application of thermal imaging technology was used in a device patented in 1914 to detect the presence of icebergs by R.D. Parker. Twenty years later a similar device was used to detect forest fires and the heating uniformity the manufacture of steel. The first thermal imaging camera was developed in 1947 in a joint effort between the US Military and Texas Instruments. The first military use of thermal imaging devices was as sensors during the Cold War as a warning system for an impending nuclear attack. The thermal sensors would essentially be used to detect radiation and heat from a missile.It would not be until the late 1990s that thermal imaging devices were put to use in civilian use as well as in use by individual military operators as an advanced form of night time observation and surveillance devices. On the civilian side they are used by firefighters to find the source of a fire in a building or search for trapped victims. Building maintenance people use thermal imagers to check insulation levels in buildings.
The science of Thermal Imaging Technology
Thermal images are real time visual displays of the amount of heat energy emitted or reflected by an object. Modern thermal imaging devices perform complex algorithms to interpret multiple points of the data they are receiving in order to compose a visual image. Unlike night vision scopes or cameras or the human eye, for that matter; thermal imaging devices do not rely upon the reflection of light energy to create a visible image; instead they rely on the heat signature of the object. For this reason, military helicopter pilots can use thermal imaging to navigate through a sandstorm that would virtually blind someone flying with the naked eye.Heat signatures are emitted from a variety of sources. Vegetation, rocks and manmade structures derive their heat signatures by absorbing heat from the sun during daylight hours and they in turn radiate this heat at night time. People, animals and vehicle engines create their own heat internally. As different materials absorb and release heat at different rates, these differences are interpreted by the thermal imager.A thermal imager is not looking for light and contrast between colors as a typical scope or camera does. A thermal imager sees the heat patterns and differences and renders an image based upon the minute differences in the heat signatures between different objects. These differences can be as minute as 0.01 degrees in temperature. Heat is part of the infrared spectrum but cannot typically be seen through the human eye, a typical scope or a camera. Likewise visible light which is not in the infrared spectrum cannot be seen through an infrared imaging device.
Most thermal imaging devices will display the image in black and white with shades of gray, with white generally being the hotter objects. Some thermal imaging devices will display the image in a variety of primary colors depending on the intensity of the infrared emission. Red and orange will be the warmer regions, with blue, black and violet as the colder areas. Some thermal imaging devices can invert these colors. The resulting thermal image is known as a thermogram. Reading a thermogram can take a bit of practice depending on the quality of the thermal imager and the nature of the subject. While a live target can be seen, it cannot always be easily identified. For example, a thermal imager can tell you if there is a man standing in front of you at night, but cannot necessarily give enough detail to tell if it is a friend or an enemy. This is based on the resolution of the thermal imager. Higher resolution is needed for better clarity and the resolution is typically mentioned in pixel counts such as 320 X 240, with 320 being the horizontal pixel count and 240 being the vertical for a total of 76,800 pixels. Each pixel in turn represents one of the data points with a temperature assigned to it. The pixels are the output from a circuit board with a dedicated chip that translates the viewed objects into interpretable data from the thermogram. The rule of thumb to remember is: the higher the pixel count, the better the resolution. Higher resolution will enable the user to spot smaller targets at longer distances because higher resolution gives a greater field of view. Clarity will depend on the refresh rate of the thermal imager. The refresh rate represents the number of times in a second that the thermal imaging device's hardware draws the data. This is measured in Hertz (Hz) and translates into the number of frames per second. An refresh rate greater than 50 Hz is equivalent to High Definition, whereas the 30 Hz range is considered Standard Definition.
Thermal Imaging Vs. Night Vision
"We have movement on the boat. He just sat up," an infrared camera operator on board a police aircraft told his law enforcement colleagues on the ground. Those words signified the beginning of the end of the standoff between Massachusetts State Police and one of the suspects in the terrorist bombing attack on the Boston Marathon this past April in Watertown, Massachusetts. Infrared cameras mounted on a state police helicopter hovering above the suspect's location confirmed to police that he had taken refuge in a trailered boat in a backyard. Officers on site used night vision devices to monitor any activity outside the boat, but these devices could only detect what the officers were able to see. The crucial tool used in this incident by the State Police was the thermal imaging devices that detected the fugitive’s heat signature. thermal imaging devices detect heat so that police officers or military operators can pinpoint a body or other type of heat signature inside a structure through its walls. This is an ability lacking in pure night vision devices.
The human eye sees reflected light and operates on the same principle behind a camera: the energy from visible light is reflected and a detector receives it and transforms it into a visible image. A night vision scope works on this same principle by taking the available light from the moon, stars and any manmade light source in proximity and amplifying it immensely. This artificial light helps to create the visible image. At one time night vision devices were referred to as “starlight scopes”. This is the greatest strength and the greatest weakness of traditional night vision devices. Too much light will wash out the images seen through the lens; not enough light will fail to render a usable image. Supplemental artificial light may be too bright and this can cause damage to certain types of night vision equipment. As a result, traditional night vision is virtually useless during the twilight hours just before dusk or just before dawn and completely useless during the day time. There are other factors at play such as image contrast. A dark colored object against a light background or a light colored object against a dark background will show up more clearly than an object that is similar in color to its background. At night time, due to the absence of light, image contrast tends to decrease, even when a night vision device is in use. In some instances, because of the greenish hue of a night vision device, the image itself may appear murky and distorted due to image contrast thermal imaging negates these all of these problems and is completely usable regardless of whether or not the sun is shining. It is true 24-hour sighting equipment, regardless of the time of day or season of the year.
Unlike night vision scopes or cameras or the human eye, for that matter; thermal imagers do not rely upon the reflection of light energy to create a visible image; instead they rely on the heat signature of the object. Heat signatures are emitted from a variety of sources. Vegetation, rocks and manmade structures derive their heat signatures by absorbing heat from the sun during daylight hours and they in turn radiate this heat at night time. People, animals and vehicle engines create their own heat internally. As different materials absorb and release heat at different rates, these differences are interpreted by the thermal imager. A thermal imager is not looking for light and contrast between colors. A thermal imager sees the heat patterns and differences and renders an image based upon the minute differences in the heat signatures between different objects. These differences can be as minute as 0.01 degrees in temperature. Thermal imagers work equally well during the day as they do at night. A sudden increase in visible light will not wash out what is seen through a thermal imager, because it is more of a sensor than a reflected lens. Most thermal imaging devices display the images in shades of black, white and grey, so the appearance is similar to that of a black and white television set. As stated in the introduction, it is for this reason that the police and military units rely more on thermal imaging than night vision when conducting a search for a suspect or missing person. The DEA relies on thermal imaging to detect illegal marijuana growing operations as the plants give off their own heat signature; a heat signature that is invisible to night vision devices.
thermal imaging is not confined to the world of the military and police agencies, though. Architects and Facility Maintenance Technicians use thermal imaging devices to help improve the effectiveness of heating insulation and air-conditioning of buildings. Firefighters use thermal imagers in order to see through smoke. This allows them to find trapped people or locate the base of a fire. Utility companies depend on thermal imaging to detect overheating lines and joints before there is an accident, fire or other calamity; as well as to find out if a section of the grid is not operational or damaged and becoming ineffective. thermal imaging is used by wildlife watchers who do not wish to disturb the animals while they are viewing them at night by lighting up the area with bright spotlights. Likewise, more and more hunters are starting to rely on thermal imaging for certain types of hunts, particularly when the quarry turns out to be dangerous game. Animals such as feral hogs and dangerous predators are effective at hiding in brush or even planted fields and even the best night vision devices can fail to spot them until it is too late. thermal imaging devices help hunters detect hogs and similar wild game, even when the animals are hidden from plain view, regardless if it is completely dark or the sun is shining brightly night vision has its place and is definitely a less expensive option, but thermal imaging represents a superior increase in technology and a much more viable alternative.
