Wave plates are made from materials with birefringence. The velocities of very light and common light through a birefringent material are inversely proportional to their refractive indices. The difference in speed can cause a phase difference when the two beams are recombined. At any particular wavelength, this difference depends on the thickness of the accelerometer (wave plate).The dual wavelength low-order wave plates were made of good quality crystalline quartz with quarter wave, half wave and full wave delays. All wave plates were mounted in Ø 25.4 mm black anodic alumina rings with a clear pore size of 18 mm. The polarization of the dual wavelength light source was controlled.
