FIELD: production of holograms by technology Dot-matrix. SUBSTANCE: given facility includes laser, electromechanical shutter, microlens, point diaphragm, liquid-crystal spatial light modulator, polarizer, projection lens and plate with photoresist installed in sequence along optical axis, double-coordinate device to move plate with photoresist, interface controlling double-coordinate device to move plate with photoresist and electromechanical shutter, device controlling liquid-crystal spatial light modulator and computer. EFFECT: reduced generation time of iridescent hologram, formation of holographic diffraction gratings which spatial frequency can have various values and which orientation can change smoothly. 2 dwg
