Holographic Display

For Scientific Research & Industry Modernisation.

Holographic display is the use of interference and diffraction principles to record and reproduce the real three-dimensional image of an object. The first step is to use the interference principle to record the light wave information of the object, which is the shooting process. The object is illuminated by the laser to form a diffuse object beam; another part of the laser beam as a reference beam is shot to the holographic negative, and the object beam is superimposed to produce interference, which converts the phase and amplitude of each point on the object’s light wave into intensity that varies in space, thus recording all the information of the object’s light wave using the contrast and interval between the interference stripes. The negative with the recorded interference stripes will become a hologram, or holographic photograph, after the processing procedures such as developing and fixing.
