無透鏡可見光編碼成像系統原理與分析

無透鏡可見光編碼成像系統是一種不需要透鏡的相機，取而代之的是使用一個特別設計過的的二進制編碼針孔。因為拍攝到的影像是由多個針孔成像的疊影所構成，是一張模糊的影像，又稱為編碼影像，所以我們需要透過影像演算法來重建原始的場景，演算法輸出的影像稱為解碼影像。本論文介紹了無透鏡可見光編碼成像系統的相關原理，包含編碼針孔的設計與重建演算法的原理，並且分析了不同編碼針孔以及不同重建演算法的差異與優缺點。

Lensless visible light coded aperture imaging system is a camera without lens.Instead, We design a binary coded aperture to replace the lens in the camera. Because the projection on the sensor surface is an image made up of scene images though the several pinholes, and we called this kind of blurred image received by the sensor 'coded image'. Therefore, we must use an algorithm to reconstruct the original scene, and the output of the algorithm is 'decoded image'. This paper introduces the relative theories of Lensless visible light coded aperture imaging system, including the design of the coded aperture and the principle of the reconstruction algorithm. Besides, we also analyze the dierences between distinct coded apertures and the Pros and cons of distinct reconstruction algorithms.
