<p>System for detection and depiction of objects in the path of marine vessels and for warning about objects that may constitute a risk to the navigational safety. The system includes a sweeping unit for illumination of objects within the field of view of the system, including a light source which emits a beam within the field of view of the system, an optical sensor and pulse processing unit including optical detectors for monitoring of the beam output power and generation of a start pulse for measurement of distance, for detection/reception of radiant energy reflected from objects, including measurement of distance to the reflecting object(s) based on the time delay between emitted and reflected light, including energy and peak effect of the pulses. The sweeping unit sweeps the beam and the optical detector's instantaneous field of view over the sweep area, by means of first and second sweeping mechanisms, to obtain directional information related to the instantaneous radiation direction relative to the vessel.</p> |
