Title: Obstacle detection system for vehicle, esp. helicopter
Inventor: DEFOUR MARTIN
IPC: G01S17/933
Filed: 1991-04-26
Abstract: The obstacle detector comprises a laser source which is intended to transmit rectilinearly polarised pulses at high frequency (several kilohertz), with a pulse duration of several tens of nano-seconds. The laser beam is received by a pulse cutter (2) which transforms a single pulse into one or more short pulses, transmitted in different directions (A,B,C). Each of the pulses passes through a polarisation separating lamella (3) and a quarter wave plate (4) which transforms it into a right circularly polarised beam. The beams are then transmitted to an addressing device (X,Y, 5) consisting of galvanometric mirrors or an opto-acoustic deflector and then an objective lens (6) prior to transmission in a pre-defined direction. For each pulse, the light retro-reflected by an obstacle with characteristic polarisation may then be detected.
