ABSTRACT:
An optical tracking system 10 is provided which comprises a beam source 12 which generates a light beam. The light beam travels through a splitter/filter 14 and proximate a DMD array 16. The DMD array 16 is controlled by a DMD array control system 18 which causes a single element within the DMD array to deflect the light beam towards a selected track on an optical storage medium 22. The optical storage medium 22 reflects the beam dependent upon the data stored on the selected track. The reflected beam is deflected by the DMD array 16 back to the splitter/filter 14 which separates the reflected beam from the impinging beam and directs the reflected beam to a detector 24 which discerns the information stored in the storage medium 22 responsive to the receipt of the reflected beam.
