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(x-5) and p(x,y) = rect(x) b) f(x,y) = rect(x) and p(x,y) = sinc(x) 2. Determine a filter p(x,y) to obtain an output 2(, )Tgxyf xy=∇where 222Txy∂∂
