Apparatus for and method of reading targets arbitrarily oriented in imaging workstations

摘要

An apparatus for and method of electro-optically reading targets arbitrarily oriented in a workstation, such as a dual window workstation, employs a solid-state imager for capturing return light from the targets over a field of view. The imager has an array of sensors arranged along mutually perpendicular array axes. An optical system splits the field of view into a plurality of subfields of view that extend through a workstation window to a target. One subfield is optically configured to enable the imager to capture light from the target along one array axis. Another subfield is optically configured to enable the imager to capture light from the target along the other array axis. A controller processes the captured light in both the one and the other subfields to enable the reading of the arbitrarily oriented target in the workstation independently of target orientation relative to the array axes.

1. A point-of-transaction workstation for electro-optically reading targets arbitrarily oriented in the workstation during reading, comprising:
a housing; a window supported by the housing; a solid-state imager supported by the housing, and operative for capturing return light from the targets over a main field of view, the imager having an array of sensors arranged along mutually perpendicular array axes; an optical system supported by the housing and operative for splitting the main field of view into a plurality of subfields of view that extend through the window to an arbitrarily oriented target in the workstation, and for optically configuring one of the subfields to enable the imager to capture return light from the arbitrarily oriented target with resolution optimized along one of the array axes, and for optically configuring another of the subfields to enable the imager to capture return light from the arbitrarily oriented target with resolution optimized along the other of the array axes; and a controller for controlling the imager and for processing the captured return light in both the one and the other subfields to enable the reading of the arbitrarily oriented target in the workstation independently of target orientation relative to the array axes.
