Description
Summary:	We describe the development of a totally transparent CCD based optical beam position sensing device that can measure transverse displacements with an accuracy of a few microns at a distance of many meters. The device includes on sensor DSP processing of the signal spectra with background subtraction and calibration to produce a compressed beam position, sensor address/status readout in token serial strings of sensors. The position monitoring system for the CMS Endcap Muon detector is presented as an intended application.
