Grating matters

  1. Apr 6, 2008 #1
    Hi,

    I was wondering what happens when a grating is lightened by non collimated beam.

    Could anyone tell me?

    Thanks!

    Your fringe pattern gets blurred because you are illuminating the grating with multiple wave-vectors, rather than just a single incident wave-vector.

    The resultant pattern is a convolution between the response of the grating to a single wavevector and the k-spectrum (or angular spectrum) of your incident beam.

    Claude.
