Patent number: 7068374Abstract: A phase-diverse coherent optical spectrum analyzer is presented. An optical receiver receives a first input signal and a second input signal, and produces at least a first output signal, a second output signal, and a third output signal based on mixing the first input signal and the second input signal. A processing unit isolates heterodyne components from the first output signal, the second output signal and the third output signal, wherein the heterodyne components comprise a first signal and a second signal that represent the phase-diverse nature of the optical mixing process. Phase diversity of the heterodyning between the first input signal and the second input signal is achieved by the coherent optical spectrum analyzer.Type: GrantFiled: June 9, 2003Date of Patent: June 27, 2006Assignee: Agilent Technologies, Inc.Inventors: Mohan Gurunathan, William I.

Patent number: 6707958Abstract: A biochemical assay device optically scans individual biological sample containing wells in an assay plate. The device includes an imaging system overlaying the assay plate wherein a scanning light propagates by total internal reflection within an optical waveguide. The waveguide includes a plurality of pixel locations, each aligned with a well in the assay plate, at which total internal reflection is selectively frustrated to output an incident beam of light. That light illuminates the well and causes generation of an emission beam of light that is detected by a photoreceptor. The device further includes a driver circuit that controls the selective frustration of total internal reflection at each pixel location in order to scan each well in the assay plate. A processor is also included in the device to process the detected emission beams of light generated by the scanned wells for purposes of assaying the biological sample contained in each scanned well.Type: GrantFiled: November 20, 2001Date of Patent: March 16, 2004Assignee: Agilent Technologies, Inc.Inventors: Richard D.

Patent number: 6687006Abstract: Heterodyne based optical spectrum analysis (OSA) involves mixing an input signal with a swept local oscillator signal to generate a heterodyne beat signal and then stretching the heterodyne beat signal before the signal is sampled. A system for optical spectrum analysis includes a local oscillator source, an optical coupler, a heterodyne receiver, and a processor. A circuit for stretching the heterodyne beat signal is included in the heterodyne receiver and may include a diode in series with a capacitor and a resistor or a diode in series with a capacitor and a switch. Stretching the heterodyne beat signal involves extending the duration of the signal so that the signal can be detected with fewer samples per unit of time than an unstretched signal. Another embodiment of an OSA includes a first data acquisition unit for obtaining low resolution data and a second data acquisition unit for obtaining high resolution data.Type: GrantFiled: September 28, 2001Date of Patent: February 3, 2004Assignee: Agilent Technologies, Inc.Inventors: Richard D.

Patent number: 6642498Abstract: The present invention is directed to a micromirror optical multiplexer for directing light to an array of sensors. The micromirror optical multiplexer directs light from one or more sources onto multiple, coplanar sensors for the purpose of exciting fluorescence.
