Chirped pulse phase-shifting digital holography for capturing the sequence of ultrafast optical wavefronts

Abstract

For capturing the sequence of ultrafast optical wavefronts, chirped pulse phase-shifting digital holography, where a chirped reference pulse and multiple object pulses for probing an ultrafast phenomenon are used in an on-axis optical setup, is proposed and analyzed. In this study, holograms with different polarization directions at different times are obtained using a single-shot optical pulse. The procedure for reconstructing time-separated multiple amplitude images and phase images are derived and verified by numerical simulations.
