A new type of collision avoidance sensor system to detect an obstacle in a wide area for unmannded trucks has been developed. This sensor system is composed of a semiconductor laser and a CCD camera. The sensor can detect an obstacle in wide area, because a sheet-like laser-beam is used for illumination and a CCD camera is used as a two-dimentional area sensor. The signal from the CCD camera is processed by a simple analog circuit without a complex image processing. The detected area of the sensor system can be varied in any distance and any width by the gate pulse signal which is made from the syncronising signal in video signal. It is concluded that this simple device is possible to be used as a wide-view collision avoidance sensor system with a variable detected area.
