Patent number: 9341516Abstract: A system for performing optical spectroscopy measurements includes a light source for generating an input optical beam and an interferometer. The interferometer includes a beam splitter that splits the input optical beam into first and second light beams; a first light path that directs the first light beam through a sample containing an analyte to a first output port; and a second light path that directs the second light beam to the first output port. At least one of the first and second light paths adjusts a relative phase of a corresponding one of the first and second light beams, so that the first and second light beams are out of phase at the first output port, substantially canceling background light and outputting sample light corresponding to a portion of the first light signal absorbed by the sample in the sample cell. A detection system detects the output sample light.Type: GrantFiled: August 30, 2013Date of Patent: May 17, 2016Assignee: Agilent Technologies, Inc.Inventors: Miao Zhu, Adam Kleczewski, Robert C. Taber

Publication number: 20150198482Abstract: An optical spectroscopy method and apparatus increases signal to noise ratio of detected signals. Sample light passed through a sample includes attenuated light pulses and characteristic light located between the attenuated light pulses, the characteristic light formed by interaction between light pulses incident the sample and sample molecules. The attenuated light pulses are substantially removed from the sample light emerging from the sample prior to detection, to increase signal to noise ratio of the detected signal.Type: ApplicationFiled: April 2, 2015Publication date: July 16, 2015Inventors: Miao ZHU, Robert C.

Patent number: 8681035Abstract: A microwave imaging system uses microwave radiation provided by a microwave source to image targets. The system includes an array of antenna elements that are capable of being programmed with a respective direction coefficient to direct the microwave illumination from the microwave source toward a position on the target. The antenna elements are further capable of being programmed to receive reflected microwave illumination reflected from the position on the target. A processor is operable to measure an intensity of the reflected microwave illumination to determine a value of a pixel within an image of the target. Multiple beams can be directed towards the target to obtain corresponding pixel values for use by the processor in constructing the image.Type: GrantFiled: June 8, 2005Date of Patent: March 25, 2014Assignee: Agilent Technologies, Inc.Inventors: Izhak Baharav, Robert C.

Patent number: 8628985Abstract: Light emitting devices with improved light extraction efficiency are provided. The light emitting devices have a stack of layers including semiconductor layers comprising an active region. The stack is bonded to a transparent lens having a refractive index for light emitted by the active region preferably greater than about 1.5, more preferably greater than about 1.8. A method of bonding a transparent lens to a light emitting device having a stack of layers including semiconductor layers comprising an active region includes elevating a temperature of the lens and the stack and applying a pressure to press the lens and the stack together. Bonding a high refractive index lens to a light emitting device improves the light extraction efficiency of the light emitting device by reducing loss due to total internal reflection. Advantageously, this improvement can be achieved without the use of an encapsulant.Type: GrantFiled: October 4, 2011Date of Patent: January 14, 2014Assignee: Philips Lumileds Lighting Company LLCInventors: Michael D. Camras, Michael R. Krames, Wayne L. Snyder, Frank M. Steranka, Robert C. Taber, John J. Uebbing, Douglas W. Pocius, Troy A. Trottier, Christopher H. Lowery, Gerd O. Mueller, Regina B. Mueller-Mach

Patent number: 8289199Abstract: An antenna array for use within a microwave imaging system to capture a microwave image of a target is selectively programmed to optimize one or more parameters of the microwave imaging system. The array includes a plurality of antenna elements, each capable of being programmable with a respective phase shift to direct a beam of microwave radiation toward the target such that the microwave radiation from each of the plurality of antenna elements arrives at the target substantially in-phase. To optimize a parameter of the microwave imaging system, the phase shifts of selective ones of the antenna elements are altered, while still maintaining the substantially in-phase microwave radiation at the target.Type: GrantFiled: March 24, 2005Date of Patent: October 16, 2012Assignee: Agilent Technologies, Inc.Inventors: Izhak Baharav, Robert C.
