Abstract
A telemeter is used to measure the distances between a sequence of points on a target surface. The telemeter includes an emitting source provided with a pulsed laser sending out a pencil of light energy in a determined direction of sight, a contra-rotating wedge communicating, to the pencil, a deflection along an epicycloidal type of scanning pattern in a plane perpendicular to the axis of sight, and a receiver including the same contra-rotating wedge and a photodiode. The disclosed device can be applied more particularly to a system for the detection of obstacles of a wire-shaped type.
