  • Interferometric vibration and thermal expansion compensator
    Patent number: H1370
    Abstract: A refractive index variability measuring system using a configuration of ical interferometers, mirrors, windows and receivers is desirable. The system provides an improved and a distinctive method for vibration and thermal expansion cancellation. Additionally, an improved matching of optical paths by using this system allows for growth of several measurement paths without additional mismatch of measurement and vibration canceling paths.
