PROJECTOR DISPLAY SYSTEM HAVING NON-MECHANICAL MIRROR BEAM CONTROL Russian patent published in 2021 - IPC G03B21/28 

FIELD: display systems.

SUBSTANCE: projector display system contains: a light source; the first holographic modulator illuminated with the specified light source, wherein the specified first modulator contains a module for forming holographic images, and it is made with the possibility of applying phase shifts changing in space to the light obtained from the specified light source to obtain phase-shifted light; a lens made with the possibility of transmitting light from the specified first holographic modulator and providing Fourier transform of the specified phase-shifted light to the light obtained using Fourier transform; the second modulator illuminated with the light from the specified lens and made with the possibility of modulating light from the specified lens, wherein the second modulator contains several mirrors, and it is made with the possibility of modulating the specified light obtained using Fourier transform to form an image for projecting; and a controller.

EFFECT: providing the possibility of using non-mechanical beam control.
