Abstract
An optical radar system for vehicles has a stationary receiver and a transmitter which scans the road surface ahead of the vehicle, the scan area being shifted in accordance with the direction of steering of the vehicle. The scan area is covered by periodically sweeping a narrow-beam pulse laser through the designated scan area and monitoring the return lag of pulses reflected by objects in the scan area. The scan area is centered over the longitudinal axis of the vehicle while the latter is moving straight ahead. The axis of the scan area is shifted in proportion to the orientation of the steering wheel of the vehicle.
