Zhitong Financial APP learned that on April 23, Weimei holography (WIMI.US) obtained its own R & D patent for holographic real-time imaging with an atomized particle size of 2-4 microns.

The beneficial effect of the holographic real-time imaging system provided by the patent is that the digital hologram is generated by computer instead of the traditional holographic dry plate by using a spatial light modulator, and the real-time optical reconstruction function of the hologram is realized. compared with the traditional optical holography, it has the advantages of computer interface, convenient operation, real-time display and so on. The patent holographic real-time imaging system includes an input module, a carrier module and a screen module; the input module is a hologram made by a computer The carrier module comprises a laser, a beam expanding collimating lens, a polarizer, a spatial light modulator, a polarizer and a Fourier lens. The light beam outputted by the laser is sequentially collimated by a beam expanding lens, a polarizer, a spatial light modulator, a polarizer and a Fourier lens, and the objects of the input unit hologram loaded on the screen module are displayed on the screen module.
