Abstract
A property of a magnetic sensor, deployed on a micro machined optical element and exposed to a magnetic field, changes as the position of the micro machined optical element changes with respect to a magnetic field or, alternatively, when the magnetic field changes with respect to the micro machined optical element. The electrical, optical and/or mechanical change in sensor property varies according to the position, and a measurement of the property change tracks the change in orientation of a moveable portion of the optical element.
