    en.wikipedia.org/wiki/Thermal_weapon_sight

    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.

    X-ray pulsar-based navigation and timing (XNAV) or simply pulsar navigation is a navigation technique whereby the periodic X-ray signals emitted from pulsars are used to determine the location of a vehicle, such as a spacecraft in deep space. A vehicle using XNAV would compare received X-ray signals with a database of known pulsar frequencies ...

    en.wikipedia.org/wiki/Night-vision_device

    Fusion night vision combines I² (image intensification) with thermal imaging, which functions in the medium (MWIR 3-5 μm) and/or long (LWIR 8-14 μm) wavelength range. [42] Initial models appeared in the 2000s. [32] Dedicated fusion devices and clip-on imagers that add a thermal overlay to standard I² night vision devices are available. [43]
