摘要 在本論文中主要是利用數位影像的方法，來量測透鏡之調制傳遞函數(MTF)的研究；一般光學工廠的透鏡量測方式非常耗時，且量測儀器也非常昂貴；在本論文中，我們利用電子方式來產生我們所需的測試圖案，再運用光學上MTF的計算原理及數位影像處理技巧，開發出快速且價格低廉的光學量測系統，有別於其他傳統式的量測方法。 Abstract The purpose of this study is measuring the modulation transfer function (MTF) of the lens by using the methods of the digital image. Generally, it spends much time to measure the quality of a lens in optical manufacturer, and the instruments are very expensive. In this thesis, we use the electronic methods to generate the testing target that we need. By applying the optical theories and the technologies of digital image processing, we developed this optical measuring system that is fast and low cost, and it is different from other conventional methods.
