OPTICAL RADAR TYPE PASSAGE DISCRIMINATOR

摘要

PURPOSE:To accurately discriminate possibility of passage between obstacles by determining the presence of the obstacles within a specified distance of a vehicle with a light radar with a sharp light transmission beam being emitted in the forward direction of the vehicle parallel to the side thereof. CONSTITUTION:Lights distributed with a light distributor 3 of a light radar X are propagated to a light transmitters Tr and Tl each on both sides of the front of a vehicle through optical fibers f2 and f4. A sharp light transmission beam is emitted in the forward direction of the vehicle parallel to the side thereof from the light transmitters Tr and Tl. Reflected beam from an obstacle or the like is received and fed to the radar X via the optical fiber f3. An information processing circuit 6 generates a discrimination signal to indicate whether or not the distance from an obstacle is within a specified range therefrom thereby enabling accurate discrimination of possibility of passage between obstacles without visual observation.
