Three-dimensional imaging with simultaneous reproduction of two image elements in one display pixel by linearization of intensity ratio of two images formed by any physical gear

摘要

Full spatial resolution in stereo image is reached if each (left and right) view of a three-dimensional scene is reproduced by all pixels of the display matrix. It is attractive for this purpose to simultaneously reproduce two image resolvable elements (corresponding to image elements of left and right views) in one display pixel. This paper shows how information-dependent linearization of the optical intensity ratio of left and right image elements (whose sum is submitted in the form of common optical intensity on the input of the display pixel) can be used to present corresponding elements separately in left and right observation windows. Such a linearization principle is valid regardless of the concrete physical gear of optical separation and demonstrated on the examples of optical separators on the basis of polarization, spectral, diffractive, and real amplitude modulation of light.
