Abstract (en)
[origin: WO2006059007A1] The invention concerns a system for projecting a digital video image sequence using a light beam capable of being generated by a source (1) on a 3D swivel joint (2), of low/medium power laser type or white light laser type. The system comprises a shutter microdisc (4) with slots (3), two rotary optical discs (5) and (7) digitally interlocked on an axis (12) with 3D swivel joints (6), generating vertical and horizontal scanning of the screen, the whole assembly terminated by a rectangular shutter (8). The display is achieved by successive reflections of the light beam on microscopic reflecting facets arranged on the surface of the discs (5) and (7).
