    摘要： A display apparatus includes an image forming device configured to provide image light, a polarization controller configured to adjust a polarization state of the image light provided from the image forming device, a processor configured to control the polarization controller, based on image information to be provided to a user, a polarization beam splitter provided in a first optical path where the image light travels, the polarization beam splitter configured to reflect light of a first polarization, and transmit light of a second polarization that is different from the first polarization, and a first curved mirror provided in a second optical path of first image light among the image light reflected from the polarization beam splitter and configured to focus the first image light on a first virtual plane at a first depth position.

    摘要： Variable digital optical images may be fabricated using generic optical matrices. A generic optical matrix may have pixels corresponding to color and subpixels corresponding to noncolor effects. The pixels may include first pixels corresponding to a first color and second pixels corresponding to a second color. The subpixels may include first subpixels corresponding to a first noncolor effect and second subpixels corresponding to a second noncolor effect. Individual ones of the pixels and/or subpixels of the generic optical matrix may be obliterated according to a negative while remaining pixels and/or subpixels may be preserved. The remaining pixels and/or subpixels may form an optical image corresponding to a base image. The optical image may be colored based on the remaining pixels. The optical image may exhibit noncolor effects corresponding to the remaining subpixels. The optical image may comprise a hologram or a stereo image.
