    摘要： An optical analysis system includes an optical filter mechanism disposed to receive light from a light source and configured to optically compress data carried by the light into at least one orthogonal component of the light. A detector mechanism in operative communication with the optical filter mechanism measures a property of the at least one orthogonal component to measure the data.

    摘要： Methods and systems for detecting the presence of a substance on a surface are provided. The method can include directing a modulated light beam (e.g., having a wavelength of about 3 to about 20 μm) from a light source to a beam expander such that the beam expander widens the diameter of the light beam into an expanded beam. The expanded beam can then be directed onto the surface to form an illuminated area. A specular reflection can then be detected from the illuminated area on the surface in each light cycle, and the presence of the substance on the surface can be determined.

    摘要： Disclosed is apparatus and methodology for producing thermal detectors with spectral responsivities that mimic the absorptions of chemical analytes, and whose detector characteristics approach those of conventional broad-band thermal detectors. In an exemplary arrangement, the methodology provides for modification of a known Si-based thermal detector by adding a near-infrared dye absorbing film above a reflector deposited directly on the thermal detector element. The method is general to all types of thermal detectors that can be divided into separate absorber and thermal sensor components.

    摘要： A method of using photoacoustic spectroscopy to determine chemical information about an analyte includes the steps of emitting a light ray for interaction with a sample of an analyte; transmitting the light ray through a fill fluid disposed in a detection cell, the fill fluid having molecules substantially similar to molecules of the analyte to absorb the light ray; producing a thermal wave and oscillation in the fill fluid proportional to an intensity of the light ray; including a pressure oscillation in the fill fluid by the thermal wave; and detecting the pressure oscillation by a microphone to determine information about the analyte sample.
