| 摘要 |
The invention relates to a projection device (1) for the holographic reconstruction of scenes, said projection device comprising at least one light modulation device (2, 2R, 2G, 2B) and at least one light source (4) having a sufficient amount of coherent light for generating a wavefront (8, 8R, 8G, 8B, 8L) of a scene, encoded in the light modulation device. Reproduction means (6) are used to reproduce a Fourier transformation (FT) of the light from the light source (4), modulated by the light modulation device (2, 2R, 2G, 2B), onto a screen (7). In the same way, the wavefront (8, 8R, 8G, 8B, 8L) encoded on the light modulation device (2, 2R, 2G, 2B) is represented by means of the reproduction means (6) in at least one virtual observation window (11, 11R, 11L, 24R, 24L, 28R, 28L) of an observation plane (12). In order to pan the observation window (11, 11R, 11L, 24R, 24L, 28R, 28L) according to a change in the eye position of at least one observer, at least one deflection means (18) is arranged between the light modulation device (2, 2R, 2G, 2B) and the screen (7). |
