Abstract

The Photon Doppler Velocimetry system is widely used in transient high-speed experiments, due to its advantages of non-contact measurement, low cost, high frequency response and good traceability. When the measured target accelerates from 0 to tens of km/s within a few hundred nanoseconds, its signal frequency can reach tens of GHz, so its dynamic range and time resolution capabilities are greatly challenged. The time-stretched Photon Doppler Velocimetry uses the time-stretched characteristics of pulsed lasers to achieve high-frequency signal scaling, improves the time resolution capability of the Photon Doppler Velocimetry, and breaks the Nyquist limit of analog-to-digital conversion technology. The article completes the experimental verification and system error analysis of the time-stretched Photon Doppler Velocimetry for the simulation study of the time-stretched Photon Doppler scale factor.
