Range-gated imaging system for underwater monitoring in ocean environment
https://www.sintef.no/en/publications/publication/?pubid=1648129
High-quality video observations are very much needed in underwater environments for the monitoring of several ecosystem indicators and to support the sustainable development and management of almost all activities in the ocean. Reliable video observations are however challenging to collect, because...

Real-time super-resolved 3D in turbid water using a fast range-gated CMOS camera
https://www.sintef.no/en/publications/publication/?pubid=1620929
We present a range-gated camera system designed for real-time (10 Hz) 3D estimation underwater. The system uses a fast-shutter CMOS sensor (1280×1024 1280×1024 ) customized to facilitate gating with 1.67 ns (18.8 cm in water) delay steps relative to the triggering of a solid-state actively 𝑄 Q...

Design tool for TOF and SL based 3D cameras
https://www.sintef.no/en/publications/publication/?pubid=1510497
Active illumination 3D imaging systems based on Time-of-flight (TOF) and Structured Light (SL) projection are in rapid development, and are constantly finding new areas of application. In this paper, we present a theoretical design tool that allows prediction of 3D imaging precision. Theoretical...
