Abstract
There exist unique situations in oceanography where the small space and time scale measurements possible with laser velocimetry are required. In this paper, we review some of the aspects of instrument development for applications in these situations. Aside from the obvious field ruggedness requirements, a number of other factors must be considered; for example, battery consumption per signal photoelectron, platforms, optical coatings, pressure windows and related birefringent considerations, velocity profiling, appropriate signal processors and automatic control including protection of photodetectors from accidental overexposure. We include a discussion of the choices made for our two systems and present example data obtained in the field.
