  1. In the paper, we describe the whole configuration of the joint transform correlator ; introduce the correlative theories of joint fourier transform in detail ; in order to achieve better correlation result, the nonlinear processing of joint transform power spectrum ( jtps ) is put forward, the effect of jtps laplace sharpening and binary processing to the correlation image is given ; the method of the best binary threshold is determined ; we analyse the correlation image, present the way that removes liquid crystal diffraction spot, direct current spot and image noise, and binarize the correlation image finally

    本論文主要對提出的聯合變換相關的整體結構進行了描述;詳細介紹了聯合傅里葉變換的相關理論;為了得到更好的相關結果,本文提出對聯合功率譜進行非線性處理的方法,給出了聯合變換功率譜的拉普拉斯銳化和譜的二值化處理對相關峰像的影響及二值化最佳閾值的確定方法;對相關峰像信息進行了分析;提出了除液晶斑、直流斑和像噪聲的方法;最後對相關峰像進行了二值化處理。
  2. The angle spectrum of inputting optical signals is received by the input surface of arrayed waveguides. whereas the diffraction process of light beam outputed in slab waveguide is a process of " composing frequency and generating image ". the reason that fraunhofer diffractive pattern can be gained on outputting waveguide surface is that output ends of arrayed waveguide distribute on the arch structure which leads bent phase factor to offset the quadratic phase factor in fresnel diffraction

    輸入平板波導內束的過程是「分頻成譜」的過程,在陣列波導的輸入面接收到的是輸入信息的角譜;而輸出平板波導內束的過程則是「合頻成像」的過程,正是由於陣列波導輸出口排列分佈在圓弧形結構上,其彎曲位相因子去了菲涅耳中的二次位相因子,從而在輸出波導面上能夠得到夫瑯和費樣。
