Abstract:	實驗室發展了高動態範圍的波期檢測技術，不僅已有實驗室自製的波前檢測儀，並在過去的五年內也創造了良好的產官學合作績效，因此計畫在未來三年內發展相關波前檢測的量測應用 : 虛擬實境(Virtual Reality,VR)，擴增實境(Augmented Reality， AR)和混和實境(Mixed Reality， MR)的頭戴式顯示器硬體產業近年來蓬勃發展，其中關鍵的微型光學投影成像系統的體積、重量與光學性能已成為頭戴式顯示技術的發展瓶頸，而在體積微小化的發展下與人眼視覺的個體差異化下，傳統的機器MTF量測已經無法有效解決量測需求，投影系統的光學檢測方面也已面臨新的挑戰與發展難題亟欲解決。另一方面，近年來人工水晶體的不斷發展下，因為新型多焦點的瞳孔子孔徑設計所衍生的Hartmann光點偵測問題使得光學檢測變得困難，也是一個在波前檢測所遇到的另一個挑戰對此，我們提出了一個三年期的研究計畫，在計劃的第一年致力於改善目前的多波長量測技術，建立ＨＭＤ的光學色差模型，並利用精密光學平板玻璃來驗證此波前量測實驗的精準度，第二年致力於改善發展多波長全場光學像差量測技術，打造並使此裝置能應用在頭戴式顯示器的光學波前量測應用，並能夠有效快速的量測裝置所產生的視覺虛擬影像的深度、位置、影像品質的評估，結合眼球模型與光跡追蹤達到客觀量測的目標。並在第三年的研究將應用前兩年的多波長全像場的波前檢測技術研究成果於人工水晶體的量測研究，致力於發展量測多焦點人工水晶體與繞射型人工水晶體的同時子孔徑多焦點波前量測技術。 ;The head mount display (HMD) technology (Virtual Reality, Augmented Reality, and Mixed Reality) have been developed for years. The display inside the HMD device have been improved significantly while the optics starts to face different kind of challenges. The optical testing of the HMD is not matured. A subjective method is desired for evaluating the optical system performance of the HMD device other than the MTF testing method. In view of this, we proposed a three-year research project to overcome this issue. In the first two years, we proposed to improve the measurement dynamic range of the wavefront sensor and the mathematical modeling of the optical field of the freeform optics. By calibrating the aberration function of the lens array, adding the multiple wavelength light source, and the optical flat calibration technique, we can improve the optical system of the wavefront to be capable of measuring the HMD. We expect the wavefront sensor could be able to measure the optical field depth, the location of the image, and the wavefront quality of the image simultaneously. In the third year of research proposal, we will use the full field multiple wavelength wavefront testing technology on the intraocular lens testing. With the progression of recent intraocular lens techonolgy, the testing of intraocular lens with multifocal subaperture become nearly impossible. We will then focus the research on wavefront testing such difficult testing intraocular lens application that could include subaperture or multiple wavefront.
