Abstract
A method of eliminating the non-linearities associated with the remote feedback sensor, such as a quad position detector, used in a micro-electro-mechanical (MEM) mirror assembly. The incoming beam transmitted from a remote optical wireless link is first polarized, and then a single detector is employed to detect the polarization for the receiver. The single detector eliminates the non-linearity associated with a quad position detector, since the space between the quad detectors is eliminated.
