What is pulse photography?

It is a kind of holography with pulsed laser as light source. The pulse laser output by the pulse laser has a short duration, and the displacement between the object, the light source, the optical element and the photosensitive material is negligible during the exposure time of shooting the hologram.

Using this method to carry out holographic photography can save complicated anti-vibration measures and can shoot moving objects such as high-speed flying projectiles, wind tunnels and shock waves.
