| Summary: | 碩士 === 元智大學 === 電機工程學系 === 91 === Because of the fabrication of the Free-Form-Surface was going to be mature, the Head Mounted Display optical system composed of FFS prism was presented by Canon Inc. in 1996. Optical performance was improved by using the FFS. Then a new display device, Liquid Crystal On Silicon, appeared, the design of the HMD was greatly developed.
In this thesis, we make a product as the model and then analyze the model by CodeV, make sure that its practicability. After that, we setup a new specification; optimize the system in accordance with three surface on the FFS prism. Comparing with the original model, we successfully enlarge the Field of View and improve the optical performance.
