Three non-complex imaging arrangements are provided where in two of the
imaging arrangements a moveable carrier housing at least one objective
lens is provided and, in the other imaging arrangement, at least one
stationary objective lens and additional optical elements are provided.
Each embodiment includes at least one fixed image sensor array for
imaging thereon an optical code or target, such as a one-dimensional
barcode symbol, or label, marking, picture, etc. Each imaging arrangement
provides an extended working range of approximately 5 102 cm. The imaging
arrangements are capable of being incorporated within a barcode imager to
provide a non-complex barcode imager having an extended working range
which is comparable to or greater than the working ranges of conventional
image-based barcode imagers.
