The AN/PAS-13B thermal weapon sight (TWS) is an infrared sight developed for the United States military by Raytheon. The sight is designed for use on small arms in the U.S. military's inventory, but it can also be used as a standalone observation device. The AN/PAS-13B uses thermal imaging so that it can be used day or night. Thermal imaging ...
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.
The AN/PSQ-20 Enhanced Night Vision Goggle (ENVG) is a third-generation passive monocular night vision device developed for the United States Armed Forces by ITT Exelis.It fuses image-intensifying and thermal-imaging technologies, enabling vision in conditions with very little light.
Sights can be a simple set or system of physical markers that serve as visual references for directly aligning the user's line of sight with the target (such as iron sights on firearms), [3] or optical instruments that provide an optically enhanced—often magnified—target image aligned in the same focus with an aiming point (e.g. telescopic ...
Most modern military tactical scopes with lower power fixed magnification such as the ACOG, C79 optical sight or SUSAT (intended for rapid close-intermediate range shots rather than long-range sniping) lack such features as well. Modern fixed magnification military high-end-grade sniper telescopic sights scopes intended for long-range shooting ...
A relatively new type of telescopic sight, called prismatic telescopic sight, prismatic sight or "prism scope", replaces the image-erecting relay lenses of a traditional telescope with a roof prism design commonly found in compact binoculars, monoculars and spotting scopes.
In this both-eyes-open technique the brain superimposes the aiming reticle on the target. An added part of the technique is to shift focus after acquisition to the dominant eye/telescopic image for more accurate shooting. This overcomes the problem of centering or acquiring fast traversing targets common with all telescopic sights.
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.
