摘要： A sensor comprises two photodiodes sensitive to different wavelengths. The photodiodes or detectors are stacked in a vertical relationship to each other. A bandpass filter is provided to limit the wavelengths of light reaching the detectors. The photodiodes are formed of various combinations of materials such as AlGaN or InGaN, or different compositions of the same material. Charge detectors are coupled to each detector to provide a signal representative of the amount of radiation detected in their corresponding bandwidths. A biological sample is provided proximate the filter. A laser is used to illuminate the biological sample to create biofluorescence corresponding to intrinsic tryptophan of bacteria.

摘要： A flame detector includes a medium wavelength infrared bolometer having an array of pixel elements disposed within a housing. Optics supported by the housing and disposed with respect to the bolometer direct infrared radiation from a flame to the pixel elements of the array and direct radiation from a separate background object to the pixel elements of the array. Electronics are coupled to receive signals from the bolometer and programmed to track an intensity of radiation from the background object to monitor transmission of radiation through the optics.

摘要： An illustrative cavity ring down gas sensor includes an optical cavity for receiving a gas to be detected and at least two electromagnetic radiation sources. The first electromagnetic radiation source may emit a first beam of light having a wavelength corresponding to an absorption wavelength of the gas to be detected, and the second electromagnetic radiation source may emit a second beam of light having a second wavelength that is off of an absorption wavelength of the gas to be detected. The first beam of light may detect a cavity ring down time decay, which is related to the concentration of the gas to be detected. The second beam of light may be used to detect a baseline cavity ring down time decay, which may be used to help increase the accuracy of the sensor by, for example, helping to compensate the concentration of the gas detected by the first beam of light for sensor variations caused by, for example, sensor age, temperature or pressure changes, and/or other conditions.

摘要： An approach for obtaining a transducer mirror structure made from silicon. The structure may have a center portion and a perimeter portion that have an attachment between them which is made flexible after certain etching between the two portions. The attachment may be a web of links or legs. A force applied to the center portion at one end of the structure may cause the center portion to move relative to the perimeter portion. A piezo electric transducer or actuator may be attached to apply the force. An oxide layer, a thin layer of silicon and a mirror may be formed on the other end of the structure. The web of links or legs between the center and the perimeter portions may be established with an RIE etch of gaps through the structure to the oxide layer and an undercutting of the gaps with a KOH etch.

摘要： A pixel having a reflector situated on a substrate. A temperature sensitive resistor may be situated over at least a portion of the reflector. An insulator may be situated on the resistor. The resistor and insulator may effectively be very thin films. A flat metal mesh or grid may be situated on the insulator. The grid, insulator and resistor may be supported by two or more posts at approximately one-fourth of a wavelength from the reflector. The wavelength may be that of the radiation to be sensed by the pixel. The thermal mass of the combination of the temperature sensitive resistor, insulator and grid may be less than several times the thermal mass of the grid. Since the grid may be so thin for low noise performance and high sensitivity, the grid can have a flatness assured to a desired extent with stiffeners attached to portions of it.

摘要： A surface enhanced Raman scatter (SERS) analyte analyzer. The analyzer has floating surfaces for enhancement of the Raman scattered light from sample molecules. An injector may provide a spray of charged nanoparticles suspended in droplets of an evaporable solution into a chamber. When the solution quickly evaporates, droplets of nanoparticles are left without a supporting solution. These droplets or cloud of charged nanoparticles may then explode into a dispersion or aerosol. The charged nanoparticles may attract molecules of a sample for attachment to their surfaces. A laser light may impinge the attached molecules which may result in surface enhanced Raman scattered light received by a detector or a light spectrometer. Wavelength signatures may then be obtained from the spectrometer. The signatures may provide information about the molecules.
