Abstract

In this work, we study the imaging characteristics of an optical see-through display based on a holographic waveguide. To fabricate this device, two transmission holograms are recorded on a photopolymer material attached to a glass substrate. The role of the holograms is to couple the incident light between air and the glass substrate, accomplishing total internal reflection. The role of noise reflection gratings and shrinkage on the imaging characteristics of the device will be also explored. The holograms (slanted transmission gratings with a spatial frequency of 1690 lines/mm) were recorded on a polyvinyl alcohol acrylamide holographic polymer dispersed liquid crystal (HPDLC) material. We will show that sufficient refractive index modulation is achieved in the material, in order to obtain high diffraction efficiencies. We will demonstrate that the final device acts as an image formation system.

摘要

在这项工作中，我们研究了基于全息波导的光学透视显示器的成像特性。为了制造该器件，在附着于玻璃基板的光聚合物材料上记录了两个透射全息图。全息图的作用是在空气和玻璃基板之间耦合入射光，实现全内反射。还将探讨噪声反射光栅和收缩对器件成像特性的影响。全息图（空间频率为1690线/毫米的倾斜透射光栅）记录在聚乙烯醇丙烯酰胺全息聚合物分散液晶（HPDLC）材料上。我们将表明，在该材料中实现了足够的折射率调制，以获得高衍射效率。我们将证明最终器件可作为图像形成系统。
