Fraunhofer diffraction and Fourier transform

Click For Summary
SUMMARY

The discussion centers on the relationship between Fraunhofer diffraction patterns and Fourier transforms, specifically how the Fourier transform of an aperture yields the diffraction pattern at infinity for light passing through that aperture. Participants emphasize the need for a physical understanding of this phenomenon, with references to Goodman's "Introduction to Fourier Optics" for a clear mathematical derivation. The conversation highlights the distinction between mathematical explanations and physical interpretations, suggesting that a deeper comprehension of the underlying principles is necessary.

a Fourier transform of an aperature results the pattern of the fraunhofer diffraction fringes at infinity of light passing that aperature.

How can we understand that point physically? I tried much to think about it! but no use.

Everyone, Please give your thought about this, so I can have many views about this.

Thanks :)

I'm not sure what you mean by a 'physical' understanding; the result you mention is due to mathematically modeling the process of diffraction.

Goodman's book "Introduction to Fourier Optics" has a clear derivation of the result in chapter 4 or 5.
 
I have Hecht book, It explains the thing mathematically only, And I mean by physical understanding, the relation between the nature and the mathematical Fourier transform, For example you can relate the Curl operator with nature by saying a wire containing an electric current produces a rotating magnetic field.
