Abstract: PURPOSE: A method and a system for measuring polarization interferometer optical wavelength improving measuring bandwidth and resolution are provided to extend a measuring bandwidth and to improve the resolution by using variable phase differences. CONSTITUTION: A method for a system for measuring polarization interferometer optical wavelength improving measuring bandwidth and resolution comprise the following steps. A plurality of voltage value is produced by using a plurality of phase delay/polarizing signal. A wavelength measuring section is determined by using one or more voltage values. Absolute values of two voltage values of the other voltage values except the above voltage values are compared within the wavelength measuring section. A wavelength value is calculated by using the compared results and the wavelength measuring section.
