Homework #4.
1.
Consider a spatial filtering system (4F system)
Assume f = 1000mm and
λ
= 1μm
•
Write an expression relating the complex amplitude g(x,y) of light in
the image plane to f(x,y) and p(x,y).
•
Assuming all distances in mm sketch g(x,0) for following cases:
a) f(x,y) =
δ
(x5) and p(x,y) = rect(x)
b) f(x,y) = rect(x) and p(x,y) = sinc(x)
