US 2018/0121694 A1 · DATA READER WITH VIEW SEPARATION OPTICS

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.

Dependent claims

A method for generating image data using a data reader having an imager, the method comprising:

directing a view of the imager toward a disk, wherein the disk has alternating first reflective section and second transmissive section;
rotating the disk;
alternatingly (1) reflecting the view of the imager via the first reflective section of the disk along a first field of view and (2) passing the view of the imager through the first transmissive section of the disk along a second field of view;
at time T1, capturing a first image with the imager while the view of the imager is being reflected via the reflective section of the disk along the first field of view;
at time T2, capturing a second image with the imager while the view of the imager is being passed through the transmissive section of the disk along the second field of view.
