Phase Shift

  1. May 16, 2004 #1
    I would like to cause a phase shift in light. I would prefer to do
    so by varying the voltage to the phase shift device. Is there any existing
    system or any suggestions?

    We had a bit of difficulty with this one. I dropped a few decimal points or something.

    Lets try this one more time. I am looking for a technique to cause a variable phase shift or delay in a yellow (580 nanometer) light beam. The modulation frequency is in the order of ten megahertz, the shift need only be a minimum of two wavelengths of the yellow light.
