一個(gè)光學(xué)像直接成在光柵面上, 8Kl&_-l{b  
如果放個(gè)透鏡在光柵后面一個(gè)焦距處, >y8>OJ?A7-  
有沒有譜面(類似于fourier transform)? \

因?yàn)檫@不是平行光,所以應(yīng)該怎么分析? ;B |  
有沒有相關(guān)材料推薦學(xué)習(xí)?

Please read "Introduction to Fourier Optics" Goodman. 8fi'"

On back focal plane of the lens, there is a Spectral Strip, same as Fourier Transform. *MfH\X379

Good luck.
