Optics.org: Researchers at SINTEF, Norway, are working with partners across Europe to develop sensors and lasers for under water ToF camera. The EU project UTOFIA (Underwater Time Of Flight Image Acquisition) has a budget of €5.7M, and will continue till 2018 as part of the European research program Horizon 2020. The other partners in the project are Bright Solutions (Italy), a Fraunhofer research center (Germany), Odos Imaging (UK), Subsea Tech (France), AZTI (Spain) and DTU Aqua (Denmark).
“
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. |
