WebWe propose a new method for precisely measuring the optical phase retardation of a wave plate using modulated-polarized light. Modulated-polarized light is used such that the zeros of the system can be accurately determined. A Babinet–Soleil compensator is employed to measure the optical phase retardation. A cross-wavelength measurement is also … WebApr 16, 2024 · It is also observed that the optical phase retardation factor is linearly proportional to the applied electric field. One can easily control this phase retardation factor by switching the external applied signal electrically [5,6,7,8,9,10,11,12]. The effect of amplitude modulation is successfully increased by the successive use of two Pockels ...
