ABSTRACT:
A picture detecting sensor unit has a passive sensor resolving a field of view into picture elements having different brightness. Picture processing means receive data from the picture detecting sensor. An additional active LADAR sensor having a laser emitting a laser beam and a scanning system for scanning an area of the field of view by this laser beam provides distance signals from the radiation reflected by an object in the field of view. The scanning of the field of view by the LADAR sensor is controlled by the picture processing means associated with the passive sensor such that the scanning effected by the LADAR sensor is limited to objects detected by the passive sensor in the field of view. A common imaging optical system is provided for the LADAR sensor and the passive sensor. A beam splitter separates the beams detected by the passive sensor and the returning beams of the LADAR sensor.
