Paper Abstract

Based on Michelson interferometer principle and controlled via an elaborately designed computer program, the variation of interference order, which contains the information of refractive index and its variation, can be detected by an optical power meter and a CCD camera. According to the relation between the increment of interference order and the change in optical path difference, the refractive index of photopolymer samples can be calculated in an accurate way. Typical measurements of the refractive index of our photopolymer samples are 1.547 and 1.583 at wavelength 532nm and 457 nm, respectively.
