近年來射出成型技術在光學鏡片上的生產應用已經逐漸成為趨勢，此技術能達到鏡片快速生產的目標，而如何快速量測鏡片也是目前發展的重點。本文將針對於縮短光路與量測鏡片進行光程差的探討，期望能夠達到以鏡片光程差評估此鏡片之光學規格；故以點繞射干涉儀作為鏡片檢測平台，以共光路式的點繞射干涉儀架構隔絕震動、空氣擾動等環境影響，並捨棄使用精密且昂貴的參考透鏡，利用偏振技術設計相位移動干涉法來提升量測數據的準確性；在波前還原的過程中，本文使用澤爾尼克多項式（Zernike Polynomials）進行波前擬合，取得還原鏡片波前來進行光程差，並重覆實驗驗證此光學量測平台的可靠性，更加以探討電耦合元件(CCD)對本光學檢測平台的影響，以期對光學鏡片的量測技術有所貢獻。

Due to the fast development in injecting molding process, mass production of optical lenses has become very affordable and achievable. In the production process, efficient measurement in optical qualities has been the key research topic today. In this thesis, major efforts are contributed to the discussions of optical path difference (OPD) of lenses and setting a standard for the measurement of OPD. Based upon the principle of point-diffraction interferometer, it is well-known that little environmental influence can disturb the measured results and no costly reference lens is needed. This study investigates mainly the tests of standard plano-convex lenses via a polarization phase-shifting scheme for accuracy improvement. During the wave-front reconstruction, we use Zernike polynomials in numerical simulations and verification experiments for better data interpretation. This study confirms system reliability by repeating tests; also, it discusses the effects given by CCD camera performance. Finally, we have established an accountable reference for tests of optical lenses
