Abstract: Systems for and methods for in situ optimization of tunable light emitting diode sources are disclosed herein. During operation, the systems and methods obtain real-time feedback from an image sensor, and that feedback is used to tune the tunable LEDs. By tuning the tunable LEDs, the best values for the LED spectral output can be selected based on the feedback from the image sensor, and an image with improved contrast is obtained. Alternatively, the amount of time to obtain an image with acceptable contrast is reduced.

Abstract: Apparatus and methods for creating deposits of uniformly spaced or uniformly overlapping droplets of selected chemicals where each droplet has an a priori known amount of the selected chemical or chemicals is taught (including biological and microbial materials). In some embodiments the deposits may be used as samples of different but known concentrations that may be used to calibrate spectroscopic inspection instruments to enable such instruments to not only provide identification in situ of unknown materials but also to provide calibrated and traceable surface concentrations of such materials. In some embodiments, such calibrated instruments may be used in enhanced processes for validating the cleanliness of manufacturing surfaces such as surfaces of equipment used in the preparation of pharmaceuticals, food, or semiconductor devices. Such instruments may be used to ensure adequate purity, or non-contamination, of surfaces of products themselves or packaging materials or of locations where such products will be used. Such calibrated instruments may also be useful in detecting cleanliness of non-manufacturing surfaces where contamination may be of concern, whether they be public or private spaces such as laboratories, restaurants, airports, satellites or other spacecraft. In some embodiments, such instruments may range from deep UV instruments to far infrared instruments or beyond.

Abstract: An integrated portable sample analysis system includes a portable case including an interior panel and a spectrometer subsystem. The spectrometer subsystem includes a flip top spectrometer sample cell including first and second members each including a window aligned with each other when the first and second members are coupled together defining a predefined spacing between the windows when the first and second members are coupled together, the first and second members decoupled for manually placing a fluid sample on a the window. An analyzer behind the interior panel receives the flip top spectrometer sample cell therein when the first and second members are coupled together for analyzing the fluid sample located between the windows by directing radiation through the windows and the fluid sample. The flip top spectrometer sample cell is configured to be withdrawn out of the analyzer for cleaning of the windows. The integrated portable sample analysis system also includes a viscometer subsystem including a flip top sample viscometer cell. The flip top sample viscometer cell includes a first plate including a rail configured to constrain a fluid sample manually presented thereto between its edges by surface tension, and a second plate including a surface spaced from the rail by a predefined gap for constraining fluid to the rail by surface tension when the rail is inclined by gravity and pulls the fluid along the rail. An analysis unit is behind the interior panel receiving the flip top viscometer sample cell therein when the first and second plates are coupled together for defining the viscosity of the sample flowing along said rail, and the flip top viscometer sample cell is configured to be withdrawn out of the analysis unit for cleaning of the rail. A processing subsystem is associated with the portable case and responsive to the spectrometer subsystem and the viscometer subsystem and configured to process outputs of the spectrometer subsystem and the viscometer subsystem and to provide a report concerning the sample, its physical properties, and its viscosity.

Abstract: A method for correcting top-of-atmosphere reflectance data in high altitude imagery to a ground surface reflectance data. Transmission of light through Earth's atmosphere and its suspended load of aerosol particles degrades light within the visible through near infrared portion of the spectrum. This can severely affect the quality of the data recorded by orbiting Earth observation satellites. The method first measures the degree of atmospheric effects upon reflectance, then reverses these effects to deliver surface reflectance data and imagery cleaned of haze and thin clouds.
