Patent ID: 8294966

Claim:
Holographic reconstruction system for reconstructing a scene which comprises spatial light modulator means, which modulate a wave with holographic information, and optical wave tracking means, which give the optical path of the modulated wave in the reconstruction system a desired direction of propagation, wherein Position control means, which control tracking mirror means, whose inclination can be controlled, and which are disposed inside the reconstruction system in front of a display screen, to control a direction of reflection for reflecting the modulated wave, and Deflection mirror means, which are disposed between the display screen and the tracking mirror means such that an image of the spatial light modulator means is created on or at least near the display screen, and which guide the modulated wave through a fix light exit position of the display screen out of the reconstruction system, Where the position control means control the tracking mirror means and the deflection mirror means such that The deflection mirror means direct the reflected wave through the display screen into a desired direction of propagation, and that The length of the optical path from the tracking mirror means to the light exit position remains constant for all sections of the modulated wave, irrespective of a set inclination of the tracking mirror means.
