yes i mean one of a , b or c .
the same problem post recently , in the link below

thank you
Fourier Transform Equations:
F(νx,νy)=∫∞−∞f(x,y)exp(−i2π(νxx+νyy))dxdy
Transfer Function of Free Space (Fraunhofer Approximation):
g(x,y)=h0exp(iπ(x2+y2)/λd)F(x/λd,y/λd)
3. The Attempt at a Solution
f(x,y)=1
F(νx,νy)=∫∞−∞exp(−i2π(νxx+νyy)dxdy=δ(νx−0)δ(νy−0)...
Homework Statement The complex amplitudes of a monochromatic wave of wavelength λ in the z=0 and z=d planes are f(x,y) and g(x,y), resprctively. Assume d=104λ, use harmonic analysis to determine g(x,y) in the following cases:
(a) f(x,y) = exp{(-jπ/λ)(x+y)}
(b) f(x,y) = cos(πx/2λ)
(c)...
