Abstract

Photonic Doppler velocimetry (PDV) is a fiber-based interferometer which has been widely used in dynamic shock physics research. Although the conventional PDV systems are simple to construct, it has special requirement to the probe for getting appropriate amount of reference light. This paper proposes to change the way in which getting the reference light to construct a generally applicable photon Doppler velocimetry system. Short time Fourier transform is utilized in order to extract frequency information from the raw data recorded by the digitizer.
