Determination of the maximum recording frequency by the Precision Laser Inclinometer of an earth surface angular oscillation

For the Precision Laser Inclinometer (FPI) using the I-20A oil, a high-frequency 4 Hz boundary was determined for reliable detection of the earth’s surface angular vibrations. The proposed method makes use of the microseismic signal and its processing to expand the PLI working interval for signal re...

Description
Summary:For the Precision Laser Inclinometer (FPI) using the I-20A oil, a high-frequency 4 Hz boundary was determined for reliable detection of the earth’s surface angular vibrations. The proposed method makes use of the microseismic signal and its processing to expand the PLI working interval for signal reception and allows to record the narrow frequency-band signals originated by the Earth surface angular oscillations caused by industrial sources.
