Achieving Variable Phase Shift in Yellow Light

Click For Summary
SUMMARY

The discussion focuses on achieving a variable phase shift in yellow light (580 nanometers) using voltage modulation. The desired modulation frequency is approximately ten megahertz, with a minimum phase shift of two wavelengths. Participants suggest exploring the use of a phase plate as a potential solution for this optical challenge. The conversation highlights the technical difficulties encountered, particularly with precision in measurements.

PREREQUISITES
  • Understanding of optical phase modulation techniques

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.
