Outline
An angular dispersion-type Fabry-Perot interferometer is developed to measure the velocity spectrum. Using this interferometer, the interference fringes with different Doppler shift are separated from each other in space, then the Doppler shift arise from a single moving source or multiple moving sources can be detected, and consequently the velocity spectra are obtained. The laser-driven aluminum foil experiments are conducted by the angular dispersion-type Fabry-Perot interferometer. Different kinds of velocity spectrum are obtained as the driving laser energy is changed, including velocity spectrum without velocity dispersion in space, discrete spectrum corresponding to a few pieces of broken aluminum foil with different speed, and continuous spectrum caused by fragment cloud or jet. Moreover, the fringe splitting caused by foil/glass interface separation under shock pressure loading is also observed.
