I have corrected two simple details: 

Use of i = sqrt(-1) is better than 'j'. i is used in Mathematics instead of j
In matrix for fourier transform the minus sign was wrong in the upper value -1. It's 1.


user cems2 says: I beleive the formula used for the spherical lens is wrong. specifically the x in the exponent numerator I think should be a constant, probably unity. as it stands the formula is not symmetric in x and y.
