FIELD: holographic equipment. SUBSTANCE: method involves passing rays through object and reference paths of holographic system, so that ray passed through three-dimensional optical modulator is focused on working surface of carrier using Fourier lens. When hologram lines are recorded, flat wave front, which illuminated optical modulator is rotated within line recording plane for each next hologram. Object path of device contains mirror, which is located after extending system along ray direction. Optical modulator is designed as two-dimensional controlled transparency. Scaling afocal system is located between optical modulator and carrier. EFFECT: increased linear size of hologram recording field, increased recording density, simplified design. 2 cl, 1 dwg
