Abstract
Disclosed is a data reader and method of data reading for an imager with multiple fields of view, including directing a first field of view of the imager along a first path, directing a second field of view of the imager along a second path, and alternately selecting one of the first view or the second view via a view splitting/combining system comprising a rotating mechanism (e.g., a disk), disposed in the view path of the imager, the disk having reflective and transmissive/open portions. The system may include synchronization between rotation of the rotating disk and the imager, one synchronization comprises using a magnet on the rotating disk and a Hall sensor on a printed circuit board beside the rotating disk, the Hall sensor output then being used to synchronize image capture to motor position. Other synchronization methods are disclosed.
