Patent CA-2253610-A1 (CA)
Inventor: RUSSELL JAMES T
IPC: G06K7/10
Filed: 1997-05-08
Abstract: A system is disclosed for retrieving data from an optical image containing two-dimensional data patterns imaged onto a sensor array. Data record is an optical data layer (19) capable of selectively altering light such as by changeable transmissivity, reflectivity, polarization, and/or phase. The sensor array (27) is a layer of charge coupled devices (CCDs) arrayed in a grid pattern generally conforming to the projected data page but preferably the sensor grid is somewhat larger than the imaged data. To compensate for various optical effects, including translational and rotational offsets, magnification and distortion of the data image as it is converted to electrical data by the sensor array, raw image data is sensed on a grid larger than the page image and then electronically processed in an alignement and bit retrieval circuit (30, 32) to determine the true data corrected for displacement, rotation, magnification, and distortion. The processed, corrected data is then output to memory or throughput to applications.

Filed: 1999-01-19
Abstract: An optical gain block that is pumped by one or more pump input modules is disclosed. Each pump input module includes a pump source, a pump power control circuit and a bus interface. Each of the available pump input modules detect the presence and pump power of other available pump input modules in order to properly adjust the output power of its own pump source. By controlling the power provided by each of the available pump input modules, the gain block output will be maintained at a specified output power level while all pump input modules share in delivering the required total input pump power. Upon the insertion or removal of any pump input module, the remaining pump input modules will adjust their output power accordingly to maintain the gain block output power at the specified level.
