Digital holography at the rate of 1 000 000 frames per second (fps), which is the fastest speed in digital holography to the best of knowledge, has been achieved. High‐speed recording of digital holography needs a high‐speed camera. However, the number of available pixels is very small in general, due to the characteristics of the high‐speed camera. Then, to record the hologram with such a small number of pixels and obtain a clear phase image of the object, parallel phase‐shifting digital holography (PPSDH) was adopted. This technique was used to successfully obtain images of the phase variation of electrical discharging phenomenon at the rate of 1 000 000 fps.
