Abstract: A beam deflection layer includes: a first selective polarization conversion-splitter that splits first color light in an incident light beam into 1A color light and 1B color light having different polarization directions from each other; a first beam deflector that deflects the 1A first first color light in the light beam from the 1A first selective polarization conversion-splitter, a first selective polarization converter that converts polarization directions of the 1A first first color light and the 1B second first color light in the light beam from the 1A first beam deflector, and a 1B second beam deflector configured to deflect the 1B second first color light in the light beam from the first selective polarization converter. The first color light, the 1A color light, and the 1B color light each have a first wavelength band.

Abstract: Disclosed are a method and a system for processing a computer-generated hologram (CGH). The system for processing a CGH includes a CGH generation apparatus and a display apparatus. The CGH generation apparatus repeatedly performs a process of propagating object data from a first depth layer to a second depth layer, changing amplitude data of the object data to second predefined amplitude data, back-propagating the object data from the second depth layer to the first depth layer, and changing the amplitude data of the object data to first predefined amplitude data, and generates a CGH by using the object data.

Abstract: A transparent panel is provided. The transparent panel includes a polarization plate, a transparent diffusion plate which is disposed on one side of the polarization plate and is configured to transmit light incident from a side of the polarization plate and to reflect and diffuse a light incident from an opposite side of the polarization plate, a ¼ wavelength plate which is disposed on one side of the transparent diffusion plate and is configured to convert a polarization direction of an incident light, and a lens part which is disposed on one side of the ¼ wavelength plate. The lens part includes a lens array comprising a birefringent material having different refractive indexes according to a polarization direction of an incident light, and a refractive index alignment member configured to transmit or refract the light according to a polarization direction of a light that penetrates the lens array.
