Seismic Observation and Analysis Based on Three-Component Fiber Optic Seismometer
We demonstrate a three-component fiber optic seismometer for seismic observation, with no electronics in the sensor probe, but relying exclusively on optical fiber in the form of an unbalanced Michelson interferometer, with state-of-the-art performance ...

Validating a low-cost seismometer using a shaking table [PDF]
Ambient vibration measurement using a seismometer represent a non-invasive and non-destructive method for seismic-related studies. This method inhibits widespread applications, i.e., assessing site fundamental frequency, estimating bedrock level ...

Extending a Lippmann style seismometer's dynamic range by using a non-linear feedback circuit [PDF]
A Lippmann style seismometer (Lippmann and Gebrande, 1983) uses a single-coil velocity-feedback method in order to extend toward lower frequencies a geophone's frequency response.
