Image Sensor Module Adjustable In Six Degrees Of Freedom For Use With An Image Acquisition Device
US Patent:
6473205, Oct 29, 2002
Filed:
Jun 3, 1998
Appl. No.:
09/090041
Inventors:
Robert D. Pepe - Dracut MA
Assignee:
Agfa Corporation - Wilmington DE
International Classification:
H04N 140
US Classification:
358483, 2502521
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 systems calibration independent of the specific module and the modules 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 scanners electronic components, without requiring the replacement of the optical sensor array, and thus re-alignment.
Method And Apparatus For Maintaining Contact Between The Recording Media And Media Support Surface Of A Scanning System
US Patent:
5671005, Sep 23, 1997
Filed:
Feb 21, 1995
Appl. No.:
8/393104

Assignee:
AGFA Division, Bayer Corporation - Wilmington MA
International Classification:
B41J 247
US Classification:
347262
Abstract:
A method and apparatus for maintaining contact between the recording media and the media support surface of a scanning system. A pressure load is applied on the recording media in the immediate vicinity of a scanning laser beam, thereby ensuring surface to surface contact between the recording media and the media support surface while scanning.
Beam Scanner
US Patent:
5600477, Feb 4, 1997
Filed:
May 4, 1995
Appl. No.:
8/434963
Inventors:
Robert D. Pepe - Dracut MA
Assignee:
Bayer Corporation - Wilmington MA
International Classification:
G02B 2608
US Classification:
359220
Abstract:
A beam scanner has a beam deflector mounted within a hollow shield having a beam entrance aperture and a beam exit aperture. The beam exit aperture is sealed by a window through which the deflected beam exits the hollow shield. A spin motor rotates the hollow shield, beam deflector and the window about a spin axis. A hydraulic system maintains the periphery of the window in an undistorted condition.
