    摘要: An emission-concentration monitoring system (20)includes first and second monitor stations (22,32) which are separated by a sensing space (40) along a path (28) of a moving vehicle (26). Each station has a source of electromagnetic radiation (64) which is directed through the vehicle's exhaust plume. Each station also has a set of detectors (66) which are positioned to receive the radiation and configured to measure transmittances at wavelengths which are absorbed by molecular species of exhaust plume (e.g., hydrocarbons, nitric oxide, carbon monoxide and carbon dioxide). These sensed transmittances are converted to emission concentrations by a data processor (50) and compared to a set of emission-concentration standards. The vehicle is determined to be in violation only if its emission concentrations at both the first and second monitor stations exceeds the standards. To insure visual identification of the vehicle, images of it are formed at both stations with video cameras (42, 44) and a license plate reader (46). It has been found that the monitoring system improves testing accuracy because the first and second stations essentially form a check against each other to remove errors due, for example, to vehicular temporal variabilities.

    摘要: An imaging device (10) has a plurality of unit cells that contribute to forming an image of a scene. The imaging device includes a layer of semiconductor material (16), for example silicon, that has low noise photogate charge-mode readout circuitry (20, 21, 26, 28) (e.g., CCD or CMOS readout circuitry and structures) that is disposed upon a first surface (18) of the layer. A second, opposing surface of the layer is a radiation admitting surface of the layer. The layer has a bandgap selected for absorbing electromagnetic radiation having wavelengths shorter than about one micrometer and for generating charge carriers from the absorbed radiation. The generated charge carriers are collected by the photogate charge-mode readout circuitry. A thermal sensing element (22) is disposed above and is thermally isolated from the first surface of the layer. The thermal sensing element may be, by example, one of a bolometer element, a pyroelectric element, or a thermopile element. A layer (12) of narrower bandgap semiconductor material can also be employed with this invention, wherein the layer of narrower bandgap semiconductor material (such as InGaAs or HgCdTe) is atomically bonded to the second surface along a heterojunction interface that is continuous or apertured across the second surface. The bonded layer is used to absorb NIR and visible light.

    摘要: A radiation detecting array 10 has a frequency domain architecture wherein incident radiation is imaged in parallel by an array of radiation detectors 12-16. Each radiation detector has an associated amplitude to frequency conversion device 18-22 for providing output signals wherein the output of each photodetector is represented as a frequency within a uniquely identified band of frequencies, the specific frequency being a function of the output signal amplitude of the photodetector. The readout of one or more selected detectors is accomplished by providing a swept frequency band or bands associated with the desired detector or detectors and mixing the detector frequencies with the swept band. The frequency representing the photodetector output may be input directly to a low dispersion transmission line 30. The unit cells may include radiation detectors comprised of superconducting material and also superconducting components that inherently manifest current or voltage to frequency conversion characteristics in accordance with the Josepson effect. An array having high temperature superconducting components includes photodetectors 60, associated voltage to frequency convertors 64 and a transmission line 70 integrated upon a common substrate.

Protective pads are disposed upon a window in an optical system forming a millimeter wave image on an array of bolometer antenna sensors. The protective pads are effectively opaque to infrared and visible emissions and are aligned to shade the bolometer portion of the bolometer antennas from infrared and visible emissions, while leaving the antenna portion of each sensor in the array exposed to intercept the millimeter wave energy incident upon them.
