Hello, All.(adsbygoogle = window.adsbygoogle || []).push({});

I'm a student.

I have a problem. I need numerically calculate of the intensity distribution of the full coherent radiation in the spatial filter(cylindrical geometry) (Katron's scheme).

Input data:

Focal length of lenses F = 1 (m)

Length of the wave of radiation Lambda = 10^{-6}(m)

The size of a crack on an entrance lens b = 0.01 (m)

And it is specified, that the spatial filtration is made on 1,2,3 maximum and minimum.

My questions:

1. What is the formulation of this questions?Can i use theory of Fraunhofer diffraction?

2. What is the plane where i need to calculate the intensity(May be Fourier plane)?

Thank you very match.
