Development of holography

The method of holography has expanded from the optical field to other fields. Such as microwave holography and acoustic holography, have been greatly developed and successfully applied to industrial medical care. Holography of seismic waves, electronic waves and X-rays is also under in-depth study. Holograms are widely used. Such as shock wave used to study rocket flight, nondestructive testing of honeycomb structure of aircraft wing, etc. Laser holography, as well as the successful research of white light holography, rainbow holography and panoramic rainbow holography, enable people to see all sides of the scene. Holographic three-dimensional display is developing towards holographic color stereoscopic TV and movies.
