ABSTRACT:
An optical tracking and positioning system is provided which comprises a beam source 14 which generates a beam which is transmitted through a splitter/filter 16. The beam issues from splitter/filter 16 and is selectively deflected to areas of an optical storage medium 12 by a mirror 18 which is controlled by a mirror control system 20. The beam is transmitted from mirror 18 through correction optics 22 and reflects off the surface of the optical storage medium 12. The beam returns along a coincident path and is separated by splitter/filter 16 and directed to a detector 24 which reads the data stored in optical storage medium 12. According to a preferred embodiment of the present invention, the mirror 18 comprises a deformable mirror device 26.
