We are developing a method for single-shot chirped-pulse phase-shifting digital holography. This method is expected to enable the simultaneous acquisition of phase difference images of two ultrafast phenomena on the femtosecond order, with a time interval on the picosecond scale, in a single shot. In this study, we attempted to experimentally demonstrate this method by capturing phase difference images of two high-voltage discharge plasmas at the same time.
