A thermographic weapon sight, thermal imagery scope or thermal weapon sight is a sighting device combining a compact thermographic camera and an aiming reticle. [1] They can be mounted on a variety of small arms as well as some heavier weapons. [2] As with regular ultraviolet sensors, thermal weapon sights can operate in total darkness.

Large thermoscopes placed outdoors appeared to cause perpetual motion of contained water, and these were therefore sometimes called perpetuum mobile. [3] Galileo's own work with the thermoscope led him to develop an essentially atomistic conception of heat, published in his book Il Saggiatore in 1623.
1709 — Daniel Gabriel Fahrenheit constructed alcohol thermometers which were reproducible (i.e. two would give the same temperature) 1714 — Daniel Gabriel Fahrenheit invents the mercury-in-glass thermometer giving much greater precision (4 x that of Rømer). Using Rømer's zero point and an upper point of blood temperature, he adjusted the ...
An M16A1 rifle fitted with the AN/PVS-2 Starlight scope. First-generation passive devices developed by the US Army in the 1960s were introduced during the Vietnam War.They were an adaptation of earlier active technology and relied on ambient light instead of using an extra infrared light source.
The first ACOG model, known as the TA01, was released in 1987. [3] [4] An example was tested on the Stoner 93 in the early 1990s by the Royal Thai Armed Forces. [5]In 1995, United States Special Operations Command selected the 4×32 TA01 as the official scope for the M4 carbine and purchased 12,000 units from Trijicon. [6]
The scope base is the attachment interface on the rifle's receiver, onto which the scope rings or scope mount are fixed. Early telescopic sights almost all have the rings that are fastened directly into tapped screw holes on the receiver, hence having no additional scope base other than the receiver top itself.
A thermal imaging camera (colloquially known as a TIC) is a type of the thermographic camera used in firefighting. By rendering infrared radiation as visible light , such cameras allow firefighters to see areas of heat through smoke, darkness, or heat-permeable barriers.
