fourier lenses
解釋
傅利葉透鏡-
In the design of holographic disc storage system, we first proposed an optimized reflection configuration for sam fourier - transform hologram storage. then we designed and manufactured an asymmetrical fourier transform lens pair, which matched the parameters of slm and ccd and the system requirements. in order to achieve 1 : 1 pixel - matching of high resolution data pages ( 1024 768 ) between slm and ccd, the two lenses were designed and optimized in an iterative manner, and the combination of them reached satisfactory results with eliminated aberrations that can meet the design requirements
首先提出來用於反射式傅立葉變換體全息存儲的空間-角度復用的光路機構，然後按照slm和ccd的光學參數以及系統的工作要求提出傅立葉變換鏡頭的設計條件，為實現在1024 768幅面的1 : 1像素匹配，設計採用非對稱結構的傅立葉變換鏡頭，可以解決slm與ccd像素尺寸相差比較大的問題，使兩個鏡頭的焦距比同slm和ccd的像素尺寸比相等。 -
Awg possesses an essential function of coherence system - " composing frequency and generating image ". therefore as far as spatial frequency field is concerned, awg is an optical integration of coherent system : two slab waveguides similar to two fourier lenses of one dimension and twice fourier transform of optical signals are realized. here the arrayed waveguide region is frequency spectrum region
Awg具有相干系統的「分頻成譜、合頻成像」這一本質功能，因此若從空間頻域的角度來看， awg就是一個相干系統的光學集成：兩個平板波導類似兩個一維傅里葉透鏡，實現光信號的兩次傅里葉變換；而陣列波導區即為頻譜區。
