Abstract
A sensor comprising a support structure and an imaging device having an image sensor, such as a CCD or CMOS or N-type metal-oxide-semiconductor (NMOS or Live MOS) sensor, positioned proximate the support structure. The support structure and the imaging device can be movable relative to one another in at least one degree of freedom. The sensor can also comprise a fiduciary disposed about the support structure and identifiable by the imaging device, wherein a position of the fiduciary relative to the imaging device is caused to change with the relative movement of the support structure and the imaging device. A position module can be configured to determine a relative position of the imaging device and the support structure based on the position of the fiduciary relative to the imaging device.
