Abstract: An image sensor sub-assembly for a scanner or other image acquisition device includes an image sensor array (134) that detects light imaged by a scanner optical system and an image sensor module (130) that enables calibration of the position of the image sensor array (134) relative to the optical system. In this way, with the optical system being constructed within tolerances, the module (130) enables alignment of the image sensor array (134) to the optical system by its adjustment. Preferably, the sensor module (130) is calibrated to defined standards, making the optical system's calibration independent of the specific module and the module's calibration independent of the specific optical system used in a given scanner. Preferably, the module (130) enables positioning of the sensor array (134) with six degrees of freedom. Further, the electronic circuit board, on which the sensor array (134) is integrated, is separate from the board, on which the analog to digital converters are located. This has the advantage of enabling replacement of the analog to digital converters, a primary source of improper operation in the scanner's electronic components, without requiring the replacement of the optical sensor array, and thus re-alignment.
