Paper Abstract

High-resolution compact reflective liquid crystal displays have been developed in recent years. The eyepiece optical system is compact, but it remains difficult to achieve a very wide FOV using LCDs of this type. To achieve a wide FOV, it is preferable to use an optical system in which an intermediate image is formed. However, this intermediate-image system ends up making displays very large compared to those using the eyepiece optical system. To solve this problem, we have developed a new optical system, called the "shuttle" optical system, in which a shuttle (bidirectional) optical path is formed in a decentered FFS (free-form surface) optical system with an intermediate image. The shuttle optical system allows the intermediate-image optical system to be compact. Through the use of this shuttle optical system as well as electronic distortion-compensation, we have developed a high-resolution SXGA compact video see-through HMD with a high FOV of 76 degrees for mixed reality.
