Paper Abstract

The paper describes the application of a monolithic folded pendulum (FP) as a tiltmeter. Both the theoretical model and the experimental results of a tunable mechanical monolithic FP tiltmeter prototype are presented and discussed. Some of the most important characteristics, like the possibility of tuning its resonance frequency to values as low as 70mHz and its measured resolution of ≈ 0.1 nrad at 100mHz, are detailed. Among the first scientific results, earth tilt tides have been already observed with a monolithic FP tiltmeter prototype.
