Inertial measurement with trapped particles: A microdynamical system
We describe an inertial measurement device based on an electrodynamically trapped proof mass. Mechanical constraints are replaced by guiding fields, permitting the trap stiffness to be tuned dynamically. Optical readout of the proof mass motion provides a measurement of acceleration and rotation,...

| description | We describe an inertial measurement device based on an electrodynamically trapped proof
mass. Mechanical constraints are replaced by guiding fields, permitting the trap stiffness to be tuned
dynamically. Optical readout of the proof mass motion provides a measurement of acceleration
and rotation, resulting in an integrated six degree of freedom inertial measurement device.
We demonstrate such a device—constructed without microfabrication—with sensitivity
comparable to that of commercial microelectromechanical systems technology and show how
trapping parameters may be adjusted to increase dynamic range. |
