“The biggest problem with traditional cameras is that their range is reduced in poor visibility, particularly in coastal waters made turbid by suspended sand and clay particles. Such cameras have a very limited range under these conditions”, said Project Manager Jens Thielemann at SINTEF.
|The camera shutter is kept closed for approximately 50ns before it opens.|
When the first 50 ns is gated out, most of the backscattering
contribution to the noise is removed.
