Abstract: An Laser Airborne Depth Sounder (LADS) system for the measurement of water depth is disclosed, the system includes a transmitter and a receiver of laser light having at least two wavelengths so as to receive a first reflection from a water surface and a second reflection from a water bottom an a rotating mirror which directs the laser light to the water and receives the second reflection of the laser light from the water bottom and directs the second reflection to the receiver, where the receiver includes an optical shutter (76) adapted for selectively allowing the passage of the second reflection laser light therethrough. The shutter (76) may include a LCD matrix or mechanical light blocking elements. The LCD matrix may be arranged in a central circle (82), an inner ring (80), and an outer ring (78).
