Young's Double Slit - Fringe Width

  1. Nov 9, 2009 #1
    When measuring the fringe width of a superposition pattern from a monochromatic source - I am using a laser. What problems/inaccuracies could I have when measuring it?

    It's super small? Human error? Shot noise? H.E.P? Fabrication inadequacies? Airborne particles? Godzilla?

    It's gonna be a long list.
