Holographic molding machine A technique for recording and reproducing the wavefront of an object using interference and diffraction principles. 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 irradiated by the laser to form a diffuse object beam; The other part of the laser beam as a reference beam is shot on the holographic plate, and the object beam is superimposed to produce interference, and the phase and amplitude of each point on the object light wave is converted into the intensity of the change in space by the rapid production line of the press, so as to record the information of the object light wave by the contrast and interval between the interference fringe.

The plate recording the interference fringes becomes a hologram, or hologram, after the development, fixing and other processing procedures. The second step is to use the diffraction principle to reproduce the light wave information of the object, which is the imaging process: the hologram is like a complex grating, under the coherent laser irradiation, the diffraction light wave of a linear record of sinusoidal hologram can generally give two images, namely the original image (also known as the initial image) and conjugate image. The reproduced image has strong three-dimensional sense and real visual effect. One part of the hologram records the light information of each point on the object, so in principle one part of it can reproduce the entire image of the original object, and multiple different images can be recorded on the same negative through multiple exposures, and can be displayed separately without interference.

The principles of holography apply to various forms of waves, such as X-rays, microwaves, sound waves, and electron waves. As long as these fluctuations are sufficiently coherent in forming the interference pattern. Optical holography is expected to be applied in stereoscopic film, television, exhibition, microscopy, interferometry, projection lithography, military reconnaissance, underwater exploration, metal exploration, preservation of precious historical relics, works of art, information storage, remote sensing, research and recording of instantaneous phenomena and instantaneous processes with rapid changes in physical states.

A technique for recording and reproducing the wavefront of an object using interference and diffraction principles. Different from the veneer hot press, 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 irradiated by the laser to form a diffuse object beam; The other part of the laser beam as a reference beam is shot on the holographic plate, and the object beam is superimposed to produce interference, and the phase and amplitude of each point on the object's light wave is converted into a spatially changing intensity, so that the contrast and interval between the interference fringes are used to record the information of the object's light wave.

The plate recording the interference fringes becomes a hologram, or hologram, after the development, fixing and other processing procedures. The second step is to use the diffraction principle to reproduce the light wave information of the object, which is the imaging process: the hologram is like a complex grating, under the coherent laser irradiation, the diffraction light wave of a linear record of sinusoidal hologram can generally give two images, namely the original image (also known as the initial image) and conjugate image.
