I am doing an experiment in the lab at the moment on laser doppler anemometry and a few questions have popped into mind, was wondering if anyone had any ideas/insights on them:
Direct detection of the Doppler frequency shift using conventional prism or grating spectrometers is not usually practical, why? How could I show this?
Also, why use just one beam? And not two for laser doppler anemometry?
