Surface Micro-Reflector Array for Augmented Reality Display

Abstract

Geometric optical waveguide display can significantly miniaturize the augmented reality eyeglasses, but suffers from the ghost image. In this paper, a method using surface micro-reflector array is proposed, which can dramatically suppress the ghost image. The transmission and expansion of the light bearing image are completed by using planar waveguide and micro-reflector array embedded in the surface layer of waveguide. The image quality is improved by using the dual channel to eliminate ghost image. The imaging process of optical system is modeled and simulated. The surface micro-reflector array waveguide element of 3 mm thickness is prepared for verification. The whole optical system has the advantages of simple structure, easy preparation and high structural strength. The display field of view is shown to be 25°× 25°, and the size of the full field of view area is 15 mm with even light distribution. What's more, the uniformity of imaging intensity is better than 20%, and the image is clear without ghost image, which can effectively realize the fusion of the virtual image and the real environment. Thus, the efficiency of augmented reality is greatly improved, and the danger of human eye safety is effectively avoided.

Application of Rhino Modeling Software in Product Fading Surface Modeling Design from the Perspective of Computer

“…Among them, f(T) is the local texture feature of the visual image of product fading surface modeling, s � (c−v)/(c + v), which represents the scale factor of Harris corner detection. To sum up, the block template matching of product fading surface modeling is carried out, and the modeling design is carried out according to the block template matching results [20,21].…”

Visually clear diffusive light panel with embedded semi-reflective rough-surface planar outcouplers

“…Thin, visually transparent lighting panels that can redirect, reshape, and/or diffuse light in an engineered fashion when illuminated have been attracting attention lately. Such panels can find useful applications in many areas ranging from augmented reality devices [1][2][3][4][5][6], transparent displays [7][8][9], solar energy harvesting [10,11], and indoor lighting [7, 12, * Author to whom any correspondence should be addressed.…”

“…Numerous novel ideas have been put forth in the making of such light-emitting transparent panels, which can be categorized into a few major groups based on their working principles. The most straightforward implementations are based on surface relief or embedded physical perturbations, on or within a transparent substrate, using micro-features [1,2,7,10,[13][14][15][16][17][18], particles [8,12], and/or buried reflecting surfaces [3,4] that abruptly disturb the propagation of light that interacts with them. These approaches can be well-suited in applications that work with a broad spectrum of light.…”
