| Abstract: | According to Lau effect,the refractive index of plane parllel transparent material is quickly measured by using an ordinary spectrometer and a pair of exactly similar course gratings.The principle and method are analyzed.Results show that the method is characterized by its high measurement accuracy,low requirements of the measurement surroundings and measured objects and high measurement speed. This method is of the practical use. |
