Methods and apparatus for monostatic pulsed time-resolved wide-field-of-view underwater laser imaging. In embodiments, a rotatable optical assembly consisting of a single pyramid mirror and optical ports for each facet is used to both direct a transmitted pulsed laser beam to a target and focus the return signal to a high dynamic range detector, such as a photomultiplier tube, The detector output signal is sampled by a high-speed digitizer and can be processed to generate three-dimensional images.

Underwater mono-static laser imaging

A system includes a UV light source and an optical medium coupled to receive UV light from the UV light source. The optical medium is configured to emit UV light proximate to a surface from which biofouling is to be removed once the biofouling has adhered to the protected surface. A method corresponds to the system.
