Ultralow Speed Measurement by Laser Doppler Velocimetry
A ultralow speed measurement system and the experimental results are reported. Its optical system is a four beam two focus differential laser Doppler velocimetry system (LDV) and the signal processing system uses a dynamic phasemeter. The measurement range can be from 1 nm/s to 300 mm/s.
