연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

Abstract ▼ AI-Helper 아이콘AI-Helper

A new method to design a see-through off-axis head-mounted-display (OA-HMD) optical system with an ellipsoidal surface is proposed, in which a tilted ellipsoidal surface is used as the combiner, which yields the benefits of easier fabrication and testing compared to a freeform surface. Moreover, we ...

제안 방법

  • The ellipsoidal combiner satisfies a “pupil-stop conjugate” requirement between the stop (exit pupil) and intermediate pupil, so that the aberration field is uniformly distributed, which reduces the generation of aberration and enables a simplified structure of the relay lens group. By analyzing the intermediate image and the intermediate pupil parameters, a relay lens group consisting of 7 pieces of coaxial relay lenses can correct tilted and curved intermediate images. When solving for the initial structure of the relay lens group, the evaluation criteria are that the spot diagram must be uniformly distributed on the aberration field, and the spot diagram’s RMS radius must be as small as possible.

이론/모형

  • Tolerance analysis is a tradeoff among the performance requirements of an optical system, processing costs of the optical elements, and assembly costs of an optical system, thereby determining its processing parameters and assembly requirements [10]. The tolerance analysis of the OA-HMD optical system uses 1000 Monte Carlo simulations to analyze the MTF value of the 3-mm subpupils, and uses the tolerance value of the OA-HMD optical system calculated by data from the Zemax software. It is obvious that the optical system has a loose tolerance and can be assembled easily.
