MTF Measurement and Analysis of Imaging Sensor

[[abstract]]本論文研究方向分為兩部分來探討： 第一部分：調制傳遞函數(Modulation Transfer Function MTF)是評價光學系統成像品質優劣的重要指標，它能反映出光學系統的空間頻率響應特性。本論文主要在探討影像感測器之調制傳遞函數量測，利用刀口邊緣(Knife Edge)及狹縫(Slit)做為量測圖樣，進行影像感測器量測，以影像感測器的奈奎斯特頻率(50 lp/mm)所對應的調制傳遞函數做為實驗量測值，探討不同量測方法之優劣分析其結果。 第二部分：此研究主要是運用成像光學模擬軟體Code V設計中繼影像光學系統(Intermediate Optics System)，分別設計兩組鏡頭，前組鏡頭為十倍變焦鏡以及後組鏡頭為像高放大鏡組，藉由中繼光學系統達成縮小化數位影像模組之目的。[[abstract]]This research is divided into two parts: The first part: MTF is to evaluate the quality of the optical imaging system is an important indicator of the merits it can reflect the spatial frequency response characteristics of the optical system In this thesis exploring the modulation transfer function of the imaging sensor measurements we use knife edge and slit as our measurement target on the imaging sensor measurement The imaging sensor Nyquist frequency (50 lp/mm) as measured experimental values to explore the pros and cons of different measurement methods and analyzed the results The second part: This study is the use of an imaging optical simulation software(Code V) to design Intermediate Optics System Two were shot the first group of 10x zoom lens and the after group of image group high magnifier with a Intermediate Optics System to achieve downsizing digital image modul
