Abstract
An optical data reader comprises a conveyor, an optical system, and a controller. The conveyor is configured to move an optical substrate in a first direction. The optical substrate includes a plurality of waveplates arranged along the first direction and along a second direction non-parallel to the first direction. The optical system is configured to observe one or more of the waveplates in its field-of-view. The optical system is mechanically coupled to at least one positioner configured to move at least a portion of the optical system in the second direction, thereby displacing the field-of-view along the second direction. The controller is coupled operatively to the conveyor and positioner and configured to vary, in the first and second directions, the relative position of the optical system versus the optical substrate, thereby controlling which of the plurality of waveplates are observed.
