Beschreibung
Zusammenfassung:	A method and system is used for detecting the presence of measuring the distance to and producing an image of, objects which, while being strongly absorbing or reflecting themselves, are hid from sight in a medium which is strongly dampening due to light dispersion, such as submersed submarines. The method provides, in addition to detecting the reflection from the surface of the object, a full acquisition of the variation of the backscatter of scanning laser pulses by the medium surrounding the object, with laser pulse transmitters operating with a much larger pulse duration, being usable for this purpose.
