相位電腦全像片:設計與應用

Abstract

本論文內容主要介紹電腦全像片的特性與設計方法，並做重建影像的電腦模擬來比較幾種設計方法的優劣。在本論文中並會以電腦模擬來進行電腦全像片在光資訊處理中的一些應用，主要的有影像去模糊濾波器、sin光柵以及具有辨識形辯影像能力的二位元純相位匹配濾波器的設計，以應用於影像還原、影像相減以及影像辨識｡

In this thesis, we introduce the encoding methods for generating computer-generated-holograms and simulate the reconstructed images of the computer-generated-holograms to compare the advantages of these encoding methods. Furthermore, we apply phase encoding methods to produce spatial filters in optical information systems，such as de-blurred spatial filters、 sine grating and binary phase matched filters for restoring the original images、image subtraction and distorted-image recognition，respectively. We have also performed the simulations of these optical information processes.
