Airborne laser image capturing system and method

摘要

The invention relates to an airborne laser image capturing system which comprises: (a) A laser source and laser focal plan array; (b) A pulse generator; (c) A scanning unit for providing to the gimbals a scanning signal for effecting a sequential stepping-scanning movement to scan an area in which the target is included; (d) A motion compensation unit; (e) A timing unit for: (e.i) Activating said pulse generator during a scanning period, thereby to produce over the target a series of illumination spots, each of said spots overlaps at least a portion of one or more adjacent spots; and (e.ii) Activating said laser focal plan array during the illumination of the target thereby to capture many of distinct spot-images (f) A correlating unit for correlating images; and (g) A combining unit for combining the spot-images to a complete image of the scanned area.
