Lidar with a high pulse repetition rate using a laser source of low pulse repetition rate

摘要

The invention relates to the field of active detection with a laser source, more particularly to the detection of high-voltage cables. The lidar according to the invention includes means (1) for transmitting a laser beam (10) along a sighting axis ( DELTA ), means for optical multiplexing (4) of this beam in order to create n transmission and reception light channels, means (2, 3) of separating the energy transmitted and the energy received by backscattering of the beam (10) on an obstacle (C), means of receiving (6 to 8) and of processing (9) the energy received in order to deliver a signal to visual display means, and visual display means, scanning means (5) common to the transmission (1) and reception (6 to 8) means. Application to helicopter flying. IMAGE
