Abstract:
1. A method for reading an optical code on an object in a view volume from multiple directions, comprising the steps of: positioning a first imager and a second imager within a reader housing and in at least approximately co-planar positions such that the first and second imagers are mountable on a common circuit board; directing a first field of view of the first imager via a first mirror set from a position of the first imager into the view volume from a first perspective onto a first side of the object; directing a second field of view of a first predetermined section of the second imager via a second mirror set from a position of the second imager into the view volume from a second perspective onto a second side of the object; directing a third field of view of a second predetermined section of the second imager via a third mirror set from a position of the second imager into the view volume from a third perspective onto a third side of the object; capturing a first image at the first imager of the first field of view into the view volume from the first perspective; capturing a second image at the first predetermined section of the second imager of the second field of view into the view volume from the second perspective; capturing a third image at the second predetermined section of the second imager of the third field of view into the view volume from the third perspective; processing and decoding the optical code based on one or more of the first, second and third images.
