An apparatus having magnetic detection sensor deployed on a micro machined optical
element is exposed to a magnetic field to sense change in property as the micro
machined optical element is manipulated with respect to the magnetic field, and,
conversely when the magnetic field is manipulated with respect to the micro machined
optical element. The electrical, optical and/or mechanical change in sensor property
varies according to said manipulation, and telemetry created by said property change
tracks the manipulation of the moveable portion of the optical element. The system
includes a configuration capable of compensating for temperature variation.
