ABSTRACT:
An arrangement working according to the laser radar principle comprises a pulsed laser range finder (LEM) for scanning a given field of view and for the pictorial presentation of the course of a perceived obstacle for the pilot on a display, whereby a respective array of semiconductor laser diodes or, respectively, of receiving detectors is provided as a transmitter and as a receiver of the laser range finder and the scanning of the field of view occurs with a mesh network-like pattern. As a result of these measures, the expense for the individual components of the arrangement is minimized and a simple, compact structure is achieved. The arrangement is suitable for obstacle warning for aircraft, particularly for low-flying helicopters.
