| Abstract: |
A two-stage electrostatic-controlled torsion pendulum has been
developed to investigate the performances of electrostatic
inertial sensors on ground. The twist and translation motions of
the proof mass were monitored by high-precision capacitance
transducers, and were synchronously controlled by electrostatic
actuators. A new two stage pendulum using silica fiber suspension
is being constructed in our laboratory in order to improve the
sensitivity, and also to investigate the cross coupling between
the differential degrees of freedom of the inertial sensor. |
