Abstract
The use of high-frequency pulsed diodes in laser Doppler anemometry allows the separation of multiple velocity components be means of time division multiplexing. An instrument based on such a technique is optically simpler than a multicomponent continuous-wave (CW) anemometer, but electronically much more complex. By including optical fibers and optical delay lines, the electronic requirements are reduced. In this paper, the practicality of a fiber delay network is demonstrated and the equivalence of pulsed and CW optical fringes is shown. Preliminary results for a 1-dimensional pulsed system are presented.
