  • Patent number: 10337927
    Abstract: Microbolometer is a class of infrared detector whose resistance changes when the temperature changes. In this work, we deposited and characterized Germanium Oxide thin films mixed with Sn (Ge—Sn—O) for uncooled infrared detection. Ge—Sn—O were deposited by co-sputtering of Sn and Ge targets in the Ar+O environment using a radio frequency sputtering system. Optical characterization shows that the absorption in Ge—Sn—O was most sensitive in the wavelength ranges between 1.0-3.0 ?m. The transmission data was further used to determine the optical energy band gap (0.678 eV) of the thin-film using Tauc's equation. We also found the variations of absorption coefficient (1.4802×105 m-1-1.0097×107 m?1), refractive index (1.242-1.350), and the extinction coefficient (0.3255-8.010) for the wavelength ranges between 1.0-3.0 ?m. The thin film's resistivity measured by the four point probe was found to be 4.55 ?-cm and TCR was in the range of ?2.56-?2.25 (%/K) in the temperature range 292-312K.

  • Patent number: 10256600
    Abstract: The Hybrid Photonic Plasmonic Interconnect (HyPPI) combines both low loss photonic signal propagation and passive routing with ultra-compact plasmonic devices. These optical interconnects therefore uniquely combine fast operational data-bandwidths (in hundreds of Gbps) for light manipulation with low optical attenuation losses by hybridizing low loss photonics with strong light-matter-interaction plasmonics to create, modulate, switch and detect light efficiently at the same time. Initial implementations were considered for on-chip photonic integration, but also promising for free space or fiber-based systems. In general two technical options exist, which distinguished by the method the electric-optic conversion is executed: the extrinsic modulation method consists of an continuous wave source such as an LED or laser operating at steady power output, and signal encoding is done via an electro-optic modulator downstream of the source in the interconnect.

    Abstract: In some aspects, the present invention embodies both the method and apparatus for converting a pattern of irradiation to a visible image. An embodiment of the present invention provides an array of micro-electro-mechanical sensors with each sensor includes a deflectable micro-cantilever, responsive to absorbed incident radiation and to an applied repulsive electrostatic field. Associated circuitry senses a change in an output signal of the sensor as it responds to incident radiation incident upon the cantilever and provides a biasing force to deflect the cantilever and maintain the detector output signal at a desirable level. The biasing element may be a piezoelectric element, a heater or a pair of electrodes and the corresponding biasing stimulus may be stress (expansion), heat, or electrostatic change. The stimulus compensates for the effect of the infrared radiation and maintains the chosen detector output level at the same level.

  • Patent number: 10110336
    Abstract: Determining ambient noise in a device under test electromagnetic compatibility test environment is presented herein. A method can include determining, by a system comprising a processor via a radio frequency input port of the system, an ambient electromagnetic noise corresponding to the system; and in response to determining, by the system via the radio frequency input port, a radio frequency signature of a device under test, subtracting, by the system, the ambient electromagnetic noise from the radio frequency signature to obtain a normalized value representing an electromagnetic emission of the device under test. In an example, an antenna/coaxial cable has been connected to the radio frequency input port, the ambient electromagnetic noise can be determined using the antenna/coaxial cable, and a radiated/conducted electromagnetic characteristic of the device under test representing the radio frequency signature of the device under test can be determined using the antenna/coaxial cable.

  • Patent number: 10110833
    Abstract: Various techniques are provided for an infrared sensor assembly having a hybrid infrared sensor array. In one example, such a hybrid infrared sensor array may include a plurality of microbolometers and a non-bolometric infrared sensor. The non-bolometric infrared sensor may be a thermopile or other type of infrared sensor different from a bolometer-based sensor. The non-bolometric infrared sensor may be utilized to provide a more accurate and stable temperature reading of an object or area of a scene captured by the array. In some embodiments, the non-bolometric infrared sensor may also be utilized to perform a shutter-less radiometric calibration of the microbolometers of the array. An infrared sensor assembly may include, for example, the hybrid infrared sensor array, as well as a substrate including bond pads and/or appropriate circuits to obtain and/or transmit output signals from the non-bolometric infrared sensor.

  • Patent number: 10067049
    Abstract: Various technologies for measurement of properties of a particulate suspended in a gas phase via laser-induced incandescence (LII) are described herein. A beam of light can be emitted into a multi-pass optical cell using a laser. The multi-pass optical cell comprises a system of one or more mirrors that repeatedly reflects the beam through a measurement region, stimulating incandescence of particulates present in the measurement region. An LII detection system having a field of view that encompasses the measurement region then receives blackbody or quasi-blackbody radiation emitted by the incandescing particles and outputs data indicative of one or more properties of the particulates in the measurement region.
