| 摘要 |
The invention relates to a projection device and a method for holographic reconstruction of scenes comprising a light modulator (8), an imaging system (3) with at least two imaging means (4, 5, 9) and an illumination device (1) with sufficient coherent light for illumination of a hologram (2) coded in the light modulator (8). The at least two imaging means (4,5) are relatively arranged such that a first imaging means (4) is provided for the magnified imaging of the light modulator (8) on a second imaging means (5). The second imaging means (5) is provided for imaging of a plane (10) of a spatial frequency spectrum of the light modulator (8) in a viewing plane (6) comprising at least one viewing window (15). The viewing window (6) corresponds to a diffraction order of the spatial frequency spectrum. |
