Hello, All.
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.
