ABSTRACT:
A pulsed laser illumination based two camera ranging and imaging system which requires only a single axis optical aperture and is therefore suited to use on aircraft and other space and configuration limited apparatus is disclosed. The invention uses intensity coded partial images of the distant target with the partial images being obtained by a distance segregating optical modulation arrangement which separates pixel portions according to their arrival time and thereby their distance of travel from the target. The described system uses pixel by pixel processing of the segregated images as accomplished in an image array processor or general purpose computer, for example.
