The paper describes a tilt meter sensor for geophysical applications, based on Folded Pendulum (FP) mechanical sensor. Both the theoretical model and the experimental results of a tunable mechanical monolithic FP tilt meter prototype are presented and discussed. Some of the most important characteristics, like the measured resolution of ≈ 0.1 nrad at 100mHz, are detailed. Among the scientific results, earth tilt tides have been already observed with this monolithic FP tilt meter prototype.

Mechanical monolithic horizontal sensor for low frequency seismic noise measurement.

The measured natural resonance frequency of the instrument of 70 mHz with a Q=140 in air without thermal stabilization demonstrates the feasibility of a monolithic folded pendulum sensor with a natural resonance Frequency of the order of millihertz with a more refined mechanical tuning.

Low frequency, high sensitive tunable mechanical monolithic horizontal sensors

This paper describes an optimized version of the mechanical version of the monolithic tunable folded pendulum, developed at the University of Salerno, configurable both as seismometer and, in a

Monolithic folded pendulum accelerometers for seismic monitoring and active isolation systems

A new class of very low-noise low frequency force-balance accelerometers is presented, designed for advanced mirror isolation systems of interferometric gravitational wave detectors and possible applications of monolithic folded pendula in geophysical instrumentation are discussed.

Folded pendulum tiltmeter

The application of the folded pendulum (FP) as a tiltmeter is proposed and some features of it have been studied both theoretically and experimentally. First, FP could have a quite low resonance

Low-frequency seismic spectrum measured by a laser interferometer combined with a low-frequency folded pendulum

Al aser interferometer combined with a reference mirror suspended on a long-period folded pendulum is presented to measure the low-frequency horizontal seismic spectrum. One of the reflecting mirrors

Novel compact tiltmeter for ocean bottom and other frontier observations

Long-term observations conducted with large arrays of tiltmeters deployed in ocean-bottom boreholes, on the seafloor and in other hazardous regions are expected to provide rich information useful in
