Optimal Diameter Double-Slit

  1. May 26, 2005 #1
    Hi All,

    I am trying to get a interference pattern from normal daylight and was wonder if I used a VERY FINE pinhole (micron sizes) to concentrate the light into some coherence and THEN have the double-slit plate behind the pinhole plate if this would work. How do I calculate the measurements? What is the optimal pinhole size that will give the best of both worlds between most coherence and least diffraction? If the pinhole is x then how do I calculate the slit size (length & width)??? PLEASE HELP if you can...

    Thank you,
