Abstract: A method for controlling a workstation includes the following: (1) energizing a first illuminator to illuminate a first subfield of view with a first illumination pulse and subsequently energizing the first illuminator to illuminate the first subfield of view with a second illumination pulse; (2) exposing the array of photosensitive elements in the imaging sensor for a first sensor-exposure time and subsequently exposing the array of photosensitive elements in the imaging sensor for a second sensor-exposure time; and (3) processing an image captured by the imaging sensor to decode a barcode in the image. The first illumination pulse overlaps with the first sensor-exposure time for a first overlapped-pulse-duration, and the second illumination pulse overlaps with the second sensor-exposure time for a second overlapped-pulse-duration. The first overlapped-pulse-duration is different from the second overlapped-pulse-duration.

Abstract: A workstation (20) electro-optically reads targets by image capture, and includes a housing, a generally planar window (18), an imaging module, and a generally planar fold mirror (38) between the window and the module. The module has an illuminating light assembly for directing illumination light along an illumination path through the window at a target for return therefrom during reading, and an image sensing assembly for detecting return illumination light through the window along an imaging path over an imaging field of view (30) during reading. The fold mirror (18) folds the illumination and the imaging paths. The fold mirror (38) and the window (18) lie in planes that are substantially parallel to each other to prevent reflections of the illumination light off of the fold mirror (38) and the window (18) from entering the imaging field of view as virtual images that degrade target detection by the image sensing assembly.
