Supersensitive Detector of Hydrosphere Pressure Variations

Supersensitive Detector of Hydrosphere Pressure Variations

This paper presents an instrument based on an equal-arm Michelson interferometer and a frequency-stabilized helium-neon laser. It is designed to record hydrosphere pressure variations in the frequency range from 0 (conventionally) to 1000 Hz, with accuracy of 0.24 mPa at sea depths of up to 50 m. Th...
