Fourier optics for diffraction pattern

  1. Oct 6, 2010 #1
    I need to determine the diffraction pattern of 2 different kinds of prisms.
    1. For a right angled prism.
    2. For a symmetric prism

    For a right angled prism, the transmission function is exp[2ipixa]*rect(x/d)
    where d is the base width of the prism, a is a conastant. So the diffraction pattern can be found by determining the fourier transform of above function. I determined the Fourier transform using the convolution theorem.

    For a symmetric prism, the transmission function is exp[2ipia(1-|x|)]*rect(x/d).
    I am having trouble calculating the fourier transform for this function. Can someone help me please?
