    Abstract: The optical module includes a sensing member, a main body and an adjustable mechanism. The sensing member includes an optical sensor. The main body guides an external light beam into the optical sensor. The adjustable mechanism is disposed at first edges of the sensing member and the main body for combining the sensing member with the main body and adjusting the relative distance or angle between the optical sensor and the external light beam. The adjustable mechanism includes a first adjustable element and a second adjustable element. The unit adjustable amount of the adjustable mechanism is equal to a difference between a first unit displacement of the first adjustable element and a second unit displacement of the second adjustable element.

    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.
