数字全息术的速度达到每秒100万帧（fps），这是目前所知的数字全息术中最快的速度。数字全息的高速记录需要高速相机。然而，由于高速相机的特性，可用像素的数量通常非常少。然后，采用平行移相数字全息术（PPSDH）记录如此少像素的全息图并获得物体的清晰相位图像。利用该技术成功地获得了放电现象在1 000 000 fps速率下的相位变化图像。
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.
