The laser Doppler speed detection, through optical heterodyne detection to detect the Doppler frequency shift to calculate volume to be measured pace movement of objects. Therefore, light source in addition to the need to meet the requirements, space access has been poor mixing detection is also req

Regarding laser Doppler velocity measurement, but the transmitted light heterodyne survey obtains the Doppler shift quantity, figures out treats measures the mobile the speed.Therefore, the photosource except needs to satisfy the spatial collimation the request, the heterodyne survey also requests t

Laser Doppler Velocimetry, can be measured by optical heterodyne detection of Doppler frequency shift, work out the speed of the moving object to be measured. Therefore, in addition to the need to meet the requirements of space and alignment of the light source, heterodyne detection or to participat
