ABSTRACT:
An arrangement for gating receivers of electro-magnetic energy where optical gating means are not available or not as advantageous as gating the detector array outputs. Appropriate passive and active discharge paths for the detecting elements are provided. Path isolation means are provided for interconnecting detector and memory elements. The gated receivers are applied to obtaining 3-D surface measurements based on the time of flight of a transmitted energy pulse.
