Classification: G01D

Abstract:
A system for tracking the movement of an object in three dimensional space comprising:a first lens having a depth-of-field disposed along a first optical axis;a second lens having a depth-of-field disposed along a second optical axis, wherein the second optical axis is angled with respect to the first optical axis, but wherein the first and second lenses have a shared field of view in which a target object may be located;a first photosensor array disposed substantially orthogonal to the first optical axis and opposite the shared field of view;a second photosensor array disposed substantially orthogonal to the second optical axis and opposite the shared field of view; anda circuit in electrical communication with the first and second photosensor arrays, the circuit configured to evaluate and correlate electrical signals output from the first and second photosensor arrays to track the movement of an object within the shared field of view.
