Sensor for two-resonator refractometer
A. V. Dormidontov, Yu. V. Prokopenko · 2013
The differential model of a refractometer based on two-resonators with “whispering gallery” modes (CDR) is designed and validated. It is shown that the accuracy of the measurement of frequency difference should be 10 Hz, thus determination accuracy of the refractivity of air is provided at the level of 10-2N -units.
