Abstract

In this paper, the geometrical properties of the optical system for Head Mounted Display (HMD) were investigated. Also, this work deals with the concept for an optical system design bated on Diffractive Optical Elements (DOE). In designing the optical system for HMD, it is considered that the optical system should have compact, high performance, and comfortable properties while user sees the picture. In order to satisfy these requirements, we applied DOE and aspheric surfaces to the lens so that correction of color and monochromatic aberrations could be obtained. Also, the design and evaluation for the optical system were carried out using the generalized model of the human eye. Finally, it was expected to fulfill all the requirements of an HMD system.

본 논문에서는 Head Mounted Display(HMD)용 광학계의 기하학적인 특징과 회절광학소자를 이용한 HMD용 광학계 설계의 개념에 대해 논의하였다. 사용자가 영상을 볼 때 편안함을 갖도록 HMD용 광학계는 경량화, 소형화 및 고해상도를 만족해야 한다. 이러한 요구조건들을 만족시키기 위해 본 논문에서는 회절광학소자와 양면 비구면화를 적용하여 색수차와 단색수차를 보정하였다. 또한 인간의 눈을 모델링하여 일반화한 모형안을 HMD용 광학계의 설계 및 성능평가에 적용하였다.
