Abstract

An embodiment of the present application provides a method for preparing an optical imaging device with an arrayed reflective unit, including: setting one of the surfaces of the transparent sheet as a reflective surface, and connecting the transparent surface of one transparent sheet with the other transparent sheet The reflective surface of the reflective surface is bonded by glue; repeat the above process until multiple light-transmitting sheets are stacked into a laminate with a preset height; the laminate is cut into multiple laminates with the same thickness along the direction perpendicular to the reflective surface; The laminations are laid flat on a plane, and the laminations laid on the plane are spliced ​​in a way of "spiral splicing" with glue to form the first lens in the same way as the reflective surface faces; the second lens is formed in the same way ; Superimpose the first lens and the second lens in a way that the reflective surfaces are orthogonal, and bond them with glue to obtain a composite lens. The reflective surfaces of each layer of the first lens and the second lens obtained by the method are coplanar, which can achieve the imaging effect of the optical imaging device.

Description

technical field [0001] The present application relates to the technical field of spatial stereo imaging, and in particular, to a preparation method of an optical imaging device with an array reflection unit. Background technique [0002] In the prior art, the stereoscopic imaging technology mainly uses two vertical mirrors to reflect the light twice according to the law of reflection, and the light is reflected twice by the two mutually perpendicular mirrors, so that the reflected light is re-converged in the air for imaging. The orthogonal mirror structure can reflect point light sources, line light sources or surface light sources, and the reflected light is still a point light source, line light source, and surface light source after the reflected light converges in the air. This special light path reflection effect makes aerial imaging technology practical. . However, at present, the aerial imaging effect of the optical imaging element using the orthogonal mirror surfac...
