摘要： PROBLEM TO BE SOLVED: To provide an apparatus (10) for detecting and analyzing chemical and biological constituents in a sample (12). SOLUTION: The apparatus (10) for detecting constituents in the sample includes a spectrometer (18) for passively receiving emissions (22) from the sample (12). A telescope (58) and/or other optical device (70) is used to confine the filed-of-view of the spectrometer (18). A low-temperature device (28) is positioned within the field-of-view of the spectrometer (18) at an opposite side of the sample (12) from the spectrometer (18). The low-temperature device (28) provides a low-temperature background relative to the sample (12) so as to increase the emissions from the sample (12), and also to reduce the background emission.

摘要： PROBLEM TO BE SOLVED: To provide a device for detecting and analyzing chemical and biological aerosol. SOLUTION: A radiation beam is used to radiate a target cloud containing the aerosol. Radiation energy absorbed by the cloud is thermalized by collision energy transfer among molecules absorbing the radiation beam to generate heat. A wavelength of an electromagnetic beam is selected to be in resonance with absorption lines of water or an oxygen molecule in the cloud, or to be in resonance with absorption lines of a known target molecule in the heat generating cloud. Temperature elevation of the cloud increases radiation intensity of the molecule with respect to a background, and the detection of the target molecule in the aerosol is improved as a result thereof. A tracking telescope collects heat radiation generated by the radiation beam. A spectrometer receives the radiation from the cloud to generate a radiation spectrum. COPYRIGHT: (C)2005,JPO&NCIPI

解决方案：使用辐射束辐射含有气溶胶的目标云。由云吸收的辐射能量通过吸收辐射束的分子之间的碰撞能量转移而被热化，以产生热量。选择电磁波的波长与云中的水或氧分子的吸收线共振，或者与发热云中的已知靶分子的吸收线共振。云的温度升高增加了分子相对于背景的辐射强度，并且作为其结果改进了气溶胶中目标分子的检测。跟踪望远镜收集由辐射束产生的热辐射。光谱仪接收来自云的辐射以产生辐射光谱。版权所有（C）2005，JPO＆NCIPI

摘要： A technique for providing high-contrast images of defects in solar cells (10) and solar panels, by illuminating each cell under inspection with broadband infrared radiation, and then forming an image of radiation that is sepcularly reflected from the cell. Multi-junction solar cells have a metal backing layer that sepcularly reflects the illumination back into an appropriately positioned and aligned camera (14), selected to be sensitive to infrared wavelengths at which the solar cell materials are relatively transparent.

摘要： A system (38) for detecting and analyzing chemical and biological materials in a sample (12). The system (38) includes a spectrometer (42) for passively receiving emissions from the sample (12) in the terahertz frequency band to detect the materials therein. A telescope (46) or other device can be used to confine the field-of-view of the spectrometer (42). A cold surface (16) is positioned filling the field-of-view of the spectrometer (42) at an opposite side of the sample (12) from the spectrometer (42). The cold surface (16) provides a low temperature background relative to the sample (12) so as to reduce the background emission and enhance the detection of the emission from the sample (12).

摘要： A method and apparatus for monitoring the quality of a laser process such as a welding process comprises monitoring the light emitted from the weld plasma above the surface of the workpiece being irradiated by the laser beam. The size of the plasma is determined from the light emission and compared to a predetermined value of the size as determined under process and workpiece conditions that produce welds of acceptable quality. Variations of the monitored plasma size greater than a preselected value can represent unacceptable welds. Such variations can be caused by changes in the laser beam power, the workpiece speed, laser focusing problems, insufficient shield gas flow, workpiece deformation and weld contamination. The process monitors the light emission from a selected range of wavelengths that correspond to the major emission peaks of the light spectrum. The process enables in-process control.

摘要： A method and apparatus for monitoring the quality of a laser process such as a laser welding process comprises monitoring the light emitted from the weld plasma above the surface of the workpiece irradiated by the laser beam. The intensity of the light emitted from the plasma is compared to a predetermined value of the light emission as determined under process and workpiece conditions that produce welds of acceptable quality. Variations of the monitored light intensity greater than a preselected value can be valuated as unacceptable welds. Such variations can be caused by changes in the laser beam power, the workpiece speed, laser focusing problems, insufficient shield gas flow, workpiece deformation and weld contamination. The process monitors the light emission for a selected range of wavelengths that correspond to the major emission peaks of the light spectrum. The method enables in-process control of laser processes.
