Abstract

The invention provides a display apparatus and a display method, which belong to the technical field of display. The display apparatus comprises an optical device comprising a plurality of mutually independent optical units capable of refracting incident linearly polarized laser light, the refractive index of the optical units being adjustable and the refractive index of the adjacent optical unit changing to sinusoidal curve distribution; a laser source arranged at the light incident side of the optical device to emit laser beams corresponding to a to-be-displayed holographic image; a driving circuit in connection with the optical device; and a holographic image data storing unit in connection with the driving circuit. The driving circuit is used to obtain the image data of the to-be-displayed holographic image from the holographic image data storing unit, and based on the image data, adjusts the refractive index of each optical unit. According to the technical schemes of the invention, it is possible to realize the dynamic display of a holographic image.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device and a display method thereof. Background technique [0002] The traditional holographic dry plate records the amplitude and phase information in the object beam in the form of the contrast and light and dark changes of the interference fringes, forming irregular interference fringes. After photosensitive holographic dry plate, the hologram obtained by developing, fixing and other processing is equivalent to a diffraction grating, and the thickness of the grating groove is related to the shape of the object to be photographed. When the reference beam is used to irradiate the holographic dry plate, the human eye can observe the holographic dry plate in the projected light, and then the reconstructed image with the same shape as the original can be observed. [0003] The disadvantage of the prior art is that the holographic dry plate records static images,...
