hi can i ask you the solution of FT[ f(x,y) = exp{(-jπ/λ)(x+y)}] ??

ok thank you for your help, I will try to solve it if possible

yes i mean one of a , b or c . the same problem post recently , in the link below https://www.physicsforums.com/threads/optical-fourier-transform-for-propagation.836793/ thank you

yes i know that, but i want a solution of one of the cases above for better understand

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)...
