Abstract
A two-dimensional fibre-based laser Doppler velocimeter has been constructed where the orthogonal velocity distributions can be recovered either sequentially or simultaneously using a novel fibre-optic polarisation state control scheme. The scheme is described and the benefits of the two approaches are discussed. The instrument is demonstrated in a simple fluid flow experiment.Keywords
