Embodiment Construction
[0034] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some, not all, embodiments of the application. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.
[0035] In order to make a near-eye display device using a transmissive organic light-emitting device and a holographic optical element without using an optical waveguide technology and a coupling structure, and realize a near-eye display, it is first necessary to record the holographic optical element. Interference fringes are formed.
[0036] For this reason, the application provides a kind of holographic optical element recording system, see figure 1 , the holographic optical element recording...

The invention provides a holographic optical element recording system, a holographic optical element recording method, a near-to-eye display system and a near-to-eye display method. The holographic optical element recording system comprises a first lens, a glass substrate, a holographic optical element, a diffuser and a second lens which are sequentially arranged, wherein signal light passes through the first lens and then is focused to the holographic optical element attached to the glass substrate; and reference light passes through the second lens to obtain parallel reference light, and theparallel light enters the holographic optical element through the diffuser. The near-to-eye display system can be manufactured by utilizing a transmission type organic light-emitting display and theholographic optical element under the condition that an optical waveguide technology and a coupling structure are not used, so that near-to-eye display is realized.
Description
technical field [0001] The present application relates to the field of optical imaging, in particular to a holographic optical element recording system and its method, a near-eye display system and its method. Background technique [0002] Augmented reality (Augmented Reality, AR) technology is a technology that ingeniously integrates virtual information with the real world. It uses multimedia, 3D modeling, real-time tracking and registration, intelligent interaction and sensing and other technical means to integrate The generated virtual information such as text, images, 3D models, music and video is simulated and applied to the real world to supplement the real information in the real world and realize the "enhancement" of the real world. [0003] The head-mounted display for augmented reality is implemented using near-eye display technology, so it is also called a near-eye display device. When people wear the near-eye display device, they can see the virtual image being ...
