Phase and group refractive indices of air calculation by fittingnof phase difference measured using a combination of laser andnlow-coherence interferometry
Original language description
The air refractive index is an important parameter in interferometric length measurements, since it substantiallynaffects the measurement accuracy. We present a refractive index of air measurement method based on monitoringnthe phase difference between the ambient air and vacuum inside a permanently evacuated double-spaced cell. The cell is placed in one arm of the Michelson interferometer equipped with two light sources—red LED and HeNe laser, while the low-coherence and laser interference signals are measured separately. Both phase and group refractive indices of air can be calculated from the measured signals. The method was experimentally verified byncomparing the obtained refractive index values with two different techniques.
