Abstract

PURPOSE:To reduce the refractive index of a group derectly from the measurement of a frequency range by transmitting the light, which has been modulated by electric signals, into a sample to be measured so that the delay in phase of the modulated signals due to the transmission is compared with the light which has not transmitted through the sample.
