Laser-Doppler velocimeter using the technique of optical frequency shift
The principles and functions of frequency shift are discussed. A LDV system using an acousto-optic modulator as its optical frequency shift device is presented. The measurements of the highly turbulent recirculating flow in a two-dimensional duct with a single step expansion were successfully performed by employing the LDV system.
