Background

Holographic projection technology (front-projected holographic display), also known as virtual imaging technology, is a technology for recording and reproducing a true three-dimensional image of an object using the principles of interference and diffraction.

The first step is to record object light wave information by using the interference principle, namely the shooting process: the shot object forms a diffused object beam under the irradiation of laser; the other part of laser beam is used as reference beam to irradiate the holographic film and is superposed with the object beam to generate interference, and the phase and amplitude of each point on the object light wave are converted into the intensity which is changed in space, so that the contrast and interval between interference fringes are used to record all information of the object light wave. The negative film with the interference fringes becomes a hologram, or hologram, after development, fixation and other processing procedures.

The second step is to reproduce the object light wave information by using the diffraction principle, which is the imaging process: a hologram behaves like a complex grating, and the diffracted light wave of a linearly recorded sinusoidal hologram generally gives two images, an original image (also called the initial image) and a conjugate image, under coherent laser illumination. The reproduced image has strong stereoscopic impression and real visual effect. Each part of the hologram records optical information of each point on the object, so that in principle each part of the hologram can reproduce the whole image of the original object, and a plurality of different images can be recorded on the same film by multiple exposures and can be displayed separately without interference.

Holographic techniques can be subdivided into optical holographic techniques, digital holographic techniques, computer holographic techniques, microwave holographic techniques, reflection holographic techniques, acoustic holographic techniques, etc. The method is applied to various fields of display, measurement, encryption, identification and the like, and the common traditional holographic technology is optical holographic technology.
