Abstract

Holographic screen (HS) is designed for using in 3D displays. HS is produced as a hologram of converging light wave and it presents an interference pattern of the reference and the object beams as a diffraction grating with variable pitch registered in the recording medium. While a color image is projected on such screen the problem of perception of the undistorted color image by the observer is appeared (due to the inherent angular dispersion of a grating with different values for different wavelengths) because the observation zones are displaced in space for each spectrum section. The problem is solved due to recording the HS by the object beam from the set of point sources, i.e. recording lengthy in the appropriate direction diffuser. With this type of HS, the observation zones, providing an undistorted perception of full-color images, are located in the imposition of lengthy images of projectors' pupils corresponding to different spectral components of projectors' radiation beams. To form an image, different projectors can be used in the display: slide projectors, video projectors based on LCD- or DMD-panels, etc. Three-dimensional images of both static and dynamic scenes can be viewed as video films at the appropriate information flows synchronization which are received by the projector from external sources.
