Abstract

Based on modern laser interferometric methods, a laser meter has been developed, equipped with a mechanical external thermal effect compensation system designed to record hydrospheric pressure variations in the frequency range from 0 (conventionally) to 1000 Hz with an accuracy of 50 μPa.
