Abstract: A mount for an optical device, such as a linear CCD array, is disclosed. The array is mounted on a base which is supported on a frame for adjustment relative thereto. The base is slidably movable on the frame for adjustment of the array in in-track and cross-track directions. The base is movable toward and away from the frame to provide a focus adjustment of the array. In order to provide a mount which can be easily and precisely adjusted to position the array along five degrees of freedom, adjustment screws are positioned such that the position of the array can be changed along one degree of freedom without changing the position of the array along any of the other degrees of freedom.

Abstract: An image sensor sub-assembly for a scanner or other image acquisition device includes an image sensor array that detects light imaged by a scanner optical system and an image sensor module that enables calibration of the position of the image sensor array relative to the optical system. In this way, with the optical system being constructed within tolerances, the module enables alignment of the image sensor array to the optical system by its adjustment. Preferably, the sensor module 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 enables positioning of the sensor array with six degrees of freedom. Further, the electronic circuit board, on which the sensor array 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.

Abstract: A four-direction adjustable optical module including a carriage and a CCD module is disclosed. The carriage includes a coupling window for coupling with the CCD module. Each of the two sides of the CCD module includes a screw hole and an elastic device. The elastic device slightly protrudes from the surface of the coupling window. While the CCD module and the coupling window are coupled, screws are employed to screw through the CCD module and into the screw holes of the coupling windows. Therefore, the elastic devices deform by the stress from the CCD module. By adjusting the tightness of the screws, the orientation of the CCD module rotating on the Z axis can be calibrated. Thus, the adjustable optical module of the invention can be calibrated at least in four directions.
