ABSTRACT:
A birefringence measurement apparatus includes a measurement part for measuring a birefringence azimuth and a birefringence amount of an object to first and second light having different wavelengths from each other, and a determination part for calculating at least one of a birefringence azimuth and a birefringence amount to third light different in wavelength from the first and second light based on the birefringence azimuth and birefringence amount of the object to the first and second light.
