The invention discloses a focus-variable retina scanning imaging three-dimensional display device. The device comprises a left eye retina scanning imaging subsystem and a right eye retina scanning imaging subsystem, wherein the left eye retina scanning imaging subsystem and the right eye retina scanning imaging subsystem are identical in structure, and each subsystem comprises a laser light source, a scanning micromirror device, a deformation mirror and a control device; the laser light sources are RGB tricolor laser light sources; the scanning micromirror devices are micro-electro-mechanicalsystem (MEMS) scanning micromirrors; and the deformation mirrors adjust focal distances under the control of the control devices according to the demands of different users, a clear left parallax image and a clear right parallax image are formed on a left eye retina and a right eye retina respectively, and therefore clear retina scanning imaging three-dimensional display is realized.
Description
technical field [0001] The invention relates to retinal scanning imaging and three-dimensional display technology, in particular to a variable-focus retinal scanning imaging three-dimensional display device. Background technique [0002] Retinal scanning imaging technology is an emerging near-eye display technology in recent years. It uses RGB three-color laser as the light source. The three-color laser is modulated to generate beams of different pixels. The reflection and convergence of the curved mirror, the convergence point is at the center of the pupil of the human eye, so that the image is directly imaged on the retina of the human eye, without the need for the focusing function of the human eyeball, so that both myopia and hyperopia patients can watch clear projection images. However, the current retinal scanning imaging technology mostly uses a curved mirror with a fixed focal length, which cannot change the focal length according to the difference in the pupil cente...
