The photon Doppler velocimetry (PDV) spectrum is investigated in an attempt to reveal the particle parameters of ejecta from shock-loaded samples in a vacuum. A GPU-accelerated Monte–Carlo algorithm, which considers the multiple-scattering effects of light, is applied to reconstruct the light field of the ejecta and simulate the corresponding PDV spectrum. The influence of the velocity profile, total area mass, and particle size of the ejecta on the simulated spectra is discussed qualitatively. To facilitate a quantitative discussion, a novel theoretical optical model is proposed in which the single-scattering assumption is applied. With this model, the relationships between the particle parameters of ejecta and the peak information of the PDV spectrum are derived, enabling direct extraction of the particle parameters from the PDV spectrum. The values of the ejecta parameters estimated from the experimental spectrum are in good agreement with those measured by a piezoelectric probe.

“…2461 This surface ejecta process has been the subject of 2462 experimental study over a long period, and has been the 2463 subject of significant recent progress in modeling and 2464 theory, much of which has been summarized in a spe-2465 cial issue of Journal of Dynamic Behavior of Materi-2466 als [85, 86]. These experiments have been performed 2467 using a variety of shock drivers, including gas guns 2468[430,53], high explosives[84,361] and high-power 2469 lasers[173,219,484,442,489] (see Figure15). These2470 different techniques offer distinct capabilities both in the 2471 extent to which the drive pressure can be tuned to ex-2472 plore different scenarios, and the diagnostics which can 2473 be applied to the resulting ejecta.…”
