摘要： A methodology and concomitant system for the reconstruction of an object from measurements of the transmitted intensity of scattered radiation effected by irradiating the object with a source of radiation. The measurements of the transmitted intensity are both spatially sampled and limited. The transmitted intensity is related to either the absorption coefficient or diffusion coefficient, or both, of the object by an integral operator. The image is directly reconstructed by executing a prescribed mathematical algorithm, as determined with reference to the integral operator, on the transmitted intensity of the scattered radiation. In a preferred embodiment, the data is measured using a paraxial arrangement composed on a single source and a small number of on-axis and off-axis detectors with the arrangement being moved over the measurement surface to measure the set of sampled and limited data.

摘要： The present invention relates to a pyroelectric infrared ray sensor fabricated by using MEMS processes, wherein an infrared ray absorption layer disposed on the most top portion of the infrared ray sensor assembly is formed with a silicon oxide film (SiO2) to exhibit an excellent absorption efficiency with respect to the infrared wavelength band of 8 to 12 mm and function as a protective film for a sensor pixel. In addition, an infrared ray absorption layer, support arms and posts are formed in a single body to allow the sensor assembly to be robust and fabricating processes to be remarkably reduced to increase a process yield.

摘要： A system and method for THz imaging utilizing a single THz detector that detects an image of a large area and provides good spatial details (high resolution). In one aspect, the system can individually modulate a different pixel of an image. The system could be a series of masks. Each mask may include holes that may be turned on/off with a distinct pattern from all of the other holes. Once the data for each mask has been received, the data for each hole may be extracted according to its modulation pattern. Another modulation system may include a micro-mirror array that deflects the THz signal towards or away from the THz detector.

摘要： The present invention resides in an infrared identification system for identifying military vehicles as friendly or hostile. The infrared identification system includes a seed introduction system, in each friendly vehicle, that introduces trace quantities of a particular seed formulation into the vehicle's exhaust. An infrared detection system, also in each friendly vehicle, detects the spectrally-discrete thermal emissions of the seed formulation to identify those vehicles having the thermal emissions as friendly. The infrared identification system provides rapid and positive friend or foe identification of land, sea and air vehicles at long ranges without being jammed, intercepted or mimicked.

摘要： An apparatus for on-line optical monitoring of the quality and/or chemical condition of a fluid; in particular, a hydrocarbon-based fluid used in transportation and industrial applications. The apparatus includes an IR-transparent internal-reflectance-element (IRE) that has at least one essentially flat surface and at least one convex surface, and at least two IR light paths of uniquely determined central-frequency and bandwidth with light from a source entering a flat surface of the IRE, internally reflecting at least once from at least one convex surface of the IRE that can contact a fluid, exiting a flat surface of the IRE, and being received at a detector. The apparatus also includes electronics to power the source and receive output from the detector of each light path. The apparatus can be controlled to independently monitor the IR light reflected within the IRE at the uniquely determined frequency of each path, and to communicate information relevant to the IR light detected.

摘要： A method is described for providing rapid on-line analyses of chemical compositions such as chemical process streams, utilizing near-infrared (NIR) spectroscopy in combination with chemometrics. In the method, for each type of analysis to be conducted, a database is provided by analyzing a series of samples using standard laboratory analytical procedures, utilizing the results as reference values to establish quantitative calibration models from NIR spectroscopy using chemometric techniques and storing this information in a computer database. An NIR spectroscopic system is also provided comprising a transflectance or a transmittance probe coupled via fiber-optic cables to a stable white light source and a spectrograph. The probe is inserted into a test sample or chemical process stream to be analyzed, a stable white light of selected wavelength range is beamed to the probe and the spectra obtained on the spectrograph are recorded. Finally the spectra obtained are correlated to the reference data stored in the computer to obtain a rapid measurement of the analysis desired.
