Radiant energy detection system |
摘要 |
A radiant energy detection system for discriminating between radiation from a target and ambient radiation wherein optical receiver means is arranged to produce two images of the observed field which are staggered along the direction of displacement of modulating grids by an amount substantially equal to the diameter of the target image, and which includes filtering means and attenuating means to balance the radiation levels in the case of ambient background radiation.
