Reconstruction device for reconstructing a three-dimensional scene, method of generating a holographic reconstruction, hologram-bearing medium, and computational device

摘要

The device has an optical system with a light source(s) and lens. The video hologram has cells, e.g. in a matrix, with an opening(s) per cell of controlled amplitude/phase and an observation plane. An observation window in the observation plane at a periodicity interval of the reconstruction as a Fourier transform of the video hologram enables viewing of a three-dimensional scene. The window size is not greater than the periodicity interval. The device has an optical system consisting of at least one real or virtual point- and/or line-shaped, adequately coherent light source (1) and a lens (2) and the video hologram (3) consists of cells in a matrix or other regular arrangement with at least one opening per cell of controlled amplitude and/or phase and an observation plane at the location of the light source image. An observation window (5) is located in the observation plane at a periodicity interval of the reconstruction as a Fourier transform of the video hologram for observation of a three-dimensional scene (6). The size of the window is not greater than the periodicity interval.
