Abstract
The present invention utilizes laser imaging, detection and ranging (LIDAR) as an optical source for an imaging system for helmeted divers who work in highly light backscattering fluid mediums. A laser emitter and detector in waterproof enclosures(s) are mounted on the divers helmet, and send signals to a topside LIDAR processing system, which processes them and sends them back down to the diver in the form of an image of the fluid environment on a viewing screen which is attached to the diver's helmet by a hinged bracket, leaving the diver's hands free for any required tasks. The LIDAR processing equipment is operated by support personnel above the surface of the water, while the imaging equipment on the diver sends and receives signals from the remote processing equipment by wires which run along the diver's hose. The system has the effect of reducing the perceived suspended particles in the fluid medium, thereby increasing identification and detection capabilities for the diver. The viewing screen can be moved from the divers field of view by a simple hand movement in emergencies or when entering or exiting the water. The system delivers a real time, continuous image which allow…
