Abstract
A plurality of range increments are sequentially pulse-illuminated and energy reflected therefrom is received by a gated light amplifier. Timing circuitry sequentially varies the range viewed, by adjusting the time between illumination and gating on of the light amplifier to achieve enhancement, suppression or apparent uniform illumination of preselected range increments such that all ranges of interest are viewed by the light amplifier within a single integration period of a recording device.
