Precision Range-Gated Imaging Technique

A giant-pulsed laser is used to actively illuminate a distant target with a light pulse of about 60 × 10⁻⁹-sec duration. The 50 × 10⁻⁹-sec exposure of an image-converter camera is delayed the proper amount with respect to the laser to allow only the return from the target to enter the camera. It is shown that backscatter from atmospheric particles (such as snow) can be greatly reduced by this technique-
