ABSTRACT:
A low altitude optical range finder for measuring the range from an aircr or other vehicle to the sea, ground terrain or other object. A source of narrow beam ultraviolet light is attached at one point on the vehicle and illuminates the object. An electromagnetically deflecting image intensifier and photodiode array combination is attached to another point of the vehicle (remote from the first point) for measuring the angle of arrival of the reflected ultraviolet light and, thereby, the range to the object.
