ABSTRACT:
An imaging system for a linear motor that provides information concerning movement of the same along a plurality of directions, with the information concerning motion along any one direction being substantially unaffected by motion of the motor in a differing direction. In this fashion, a plurality of detectors may be mounted onto the rotor of the linear motor to sense movement along a particular direction, with the detector being insensitive to motion of the motor along a differing direction. The system includes a substantially planar surface, such as a platen, having disposed thereon a pattern forming a two dimensional grid-like array.
