Abstract

The embodiment of the invention relates to the technical field of optics. The invention discloses a depth-of-field adjusting method and device capable of achieving multiple depths of field and binocular near-to-eye display equipment. The device comprises a display device used for outputting a display image and a waveguide sheet used for receiving the display image and outputting a virtual image visible to human eyes according to the display image. The display image is coupled into the waveguide sheet in the form of light; the virtual image is coupled out from the optical waveguide in the formof light. The method comprises the steps of firstly obtaining a preset adjustment value of the depth of field of a virtual image, calculating a binocular center sight included angle of the binocular near-to-eye display equipment according to the preset adjustment value, determining an included angle between coupled-out light and the waveguide sheet according to the binocular center sight includedangle to determine an included angle between coupled-in light and the waveguide sheet, and finally adjusting the included angle between the coupled-in light and the waveguide sheet to enable the depthof field of a virtual image to be adjusted to the preset adjustment value.

Description

technical field [0001] Embodiments of the present invention relate to the field of optical technology, and in particular, to a method and device for adjusting depth of field, and a binocular near-eye display device. Background technique [0002] Augmented reality is a technology that integrates virtual information with the real world. The near-eye display device is a key link in augmented reality technology. The near-eye display device allows users to see the virtual image constructed by the computer while seeing the real world. Binocular parallax refers to the difference in the imaging of the left and right eyes when the human eye sees the same object with both eyes. It is one of the important physiological factors for the human eye to judge the distance of an object. [0003] In the process of implementing the embodiments of the present invention, the inventors found that there are at least the following problems in the above related technologies: the current binocular nea...
