INTEGRATED OPTICAL DEVICE FOR RECORDING AND REPRODUCING MICROHOLOGRAMS Russian patent published in 2013 - IPC G03H1/04 

FIELD: physics.

SUBSTANCE: integrated optical device for recording and reproducing microholograms consists of a laser light source, an optical device for splitting the original beam into a signal beam and a reference beam, an optical device for expanding the signal beam, a light spatial modulator, a Fourier transform optical system, light-sensitive material and a mechanical positioning system. The device also includes: at least one laser source of coherent radiation; a signal beam forming system, having at least one optical element for forming a signal beam, on the surface of which there is at least one composite holographic element for splitting the original beam, at least one illumination holographic element for converting the signal beam, at least one holographic Fourier transform optical element and at least one auxiliary holographic element for converting light from the spatial modulator. On the reverse side of said auxiliary holographic element, there is at least one integrated electrooptic spatial light modulator.

EFFECT: simple design and smaller dimensions of the optical device for recording microholograms.
