Laser Gated Imaging

By Raf Vandersmissen, Xenics

Laser gated imaging is a technique for night vision that offers the advantage of detecting and recognizing targets at long ranges without the need for any natural light sources. This technique can be used for imaging through atmospheric obstacles such as smoke, haze, fog, and dust, and is used in various long range observation applications including security, target identification, active polarimetry, and 3D imaging. Significant improvements have been made to light source efficiency and sensor technologies which have also furthered laser gated imaging. This article highlights the general principles of laser gated imaging, as well as the advantages of imaging in different spectral bands in visible and infrared light.
