Patent number: 7536053Abstract: Nonlinear distortions of imaging optics within a computer vision system are quantified as corrective values within a viewing window defined by a pixel array. A test artifact is displaced within an object plane through increments of measured distances and the corresponding displacements of the test artifact within an image plane are recorded within the pixel array. Comparisons are made between the actual appearances of the test artifact within the image plane and predicted appearances of the test artifact within the image plane based on the measured displacements in the object plane for determining the corrective values.Type: GrantFiled: October 27, 2004Date of Patent: May 19, 2009Assignee: Quality Vision International, Inc.Inventors: Carl Davidson-Sokal, Scott Davis

Publication number: 20060132789Abstract: A system and method for optimizing dispersion in an optical transmission line is provided. The system and method comprise measuring the amplitude of a d.c. voltage component of a synchronously demodulated data signal of at least one wavelength channel by an in-phase carrier at the baud frequency of the wavelength channel. In an alternative embodiment, the system and method comprise measuring the IF amplitude of the resulting a.c. signal of a data signal of the at least one wavelength channel comprising a received RZ signal mixed with a local oscillator, whose frequency differs from the wavelength channel baud by a relatively small amount, somewhere on the order of about 100 kHz.Type: ApplicationFiled: January 26, 2006Publication date: June 22, 2006Inventors: Carl Davidson, Robert Cordell, Yi Cai, Hongbin Zhang

Patent number: 6342961Abstract: A gain-clamped, optical amplifier includes a rare-earth doped fiber and a source of pump energy coupled to the rare-earth doped fiber. The doped fiber serves as a gain medium that is optically pumped by the pump source. A wavelength-selective optical feedback loop is coupled between input and output ports of the rare-earth doped fiber. The feedback loop supports a compensating laser signal, which is a pulsed signal located at a wavelength different from a signal wavelength.Type: GrantFiled: August 4, 2000Date of Patent: January 29, 2002Assignee: TyCom (US) Inc.Inventors: Neal S.
