摘要： The device comprises a floodlight unit and a receiver unit and a processing unit. The floodlight unit applies an infrared light to the surface of a work piece, and comprises a surface light source and a focusing lens. The receiver unit receives the infrared light reflected from the surface of the work piece, and comprises a receiver sensor and a filter, which passes the infrared light that has the wavelength which contaminants on the surface absorb. The processing unit evaluates the cleanliness of the surface of the work piece according to the absorbance of the infrared light reflected from the surface. And a receiving area of the reflected infrared light from the surface is set smaller than an applying area of the applied infrared light to the surface.

摘要： A gas analyzer system includes an optical source, an optical filter assembly, a controller, and an analyzer. The optical source generates an optical signal. The optical filter assembly includes different optical filters in which to filter the optical signal. During operation, the controller selects sequential application of each of the different optical filters in a path of the optical signal to modulate the optical signal using different frequency bands of optical energy. The modulated optical signal passes through an unknown sample. The optical analyzer analyzes the modulated optical signal after passing through the sample to detect which types of multiple different gases are present in the sample.

摘要： A method for determining the concentration of an analyte in tissues. The method involves compensating for a change in the value of an optical property of the tissues, such as, for example, the scattering coefficient, resulting from a change in the hydration status of the tissues. The method comprises the steps of: (a) measuring at least one optical property of a tissue sample at at least one wavelength at an initial time; (b) calculating the absorption coefficient and the scattering coefficient of the tissue sample at the initial time; (c) repeating the measurement of the at least one optical property of the tissue sample at at least a later time at the at least one wavelength; (d) calculating the absorption coefficient and scattering coefficient of the tissue sample at at least the later time; (e) calculating the change in the value of the absorption coefficient at the at least one wavelength to indicate the change in the water content of the tissue sample and the change in the value of the scattering coefficient to indicate both the change in the water content of the tissue sample and the change in concentration of an analyte in the tissue sample; (f) correcting the value of the scattering coefficient to account for the effect of the change in the water content of the tissue sample; and (g) calculating the concentration of the analyte by means of the corrected value of the scattering coefficient.

摘要： A postacquired spectrophotometer, for use with a sample and reference. The spectrophotometer has a filter unit, defining an axis of movement, and pluralities of designated sites and dark sites disposed in uniform relation to the axis. The designated and dark sites are disposed in alternation. Alternating designated sites have apertures and filters covering the apertures. Further, a main member, coaxial with the filter unit, has sample and reference beam paths, which are intersected by the sites. The main member has disposed, in operative relation to the actuators, an actuator sensor, which generates an integration actuator signal upon alignment with each integration actuator and a clamping actuator signal upon alignment with each clamping actuator. Moreover, a drive continuously moves the filter unit relative to the axis and beam paths. Further, a light distribution system directs light separately from the sample and reference to respective beam paths, and then to a detector, which produces a detector signal responsive to light received. Finally, means for processing the signals is provided, including a clamping circuit, integrators, and a demultiplexer.

摘要： A non-dispersive infrared gas analyzer especially adapted for measuring the concentrations of HC, CO and CO.sub.2 in a vehicle exhaust includes a sample chamber for holding a sample gas, a radiation emitter for directing a beam through the chamber and a detector for indicating the amount of radiation absorbed. A plurality of filters each of which transmit radiation at an absorption band of a gas component to be detected are alternatingly positioned in the radiation path to produce a time-multiplexed signal having concentration information for all gases. The time-multiplexed detector output is corrected for gain and offset errors "on-the-fly", without requiring demultiplexing, through the use of an analog multiplier circuit. The correction factors are themselves determined without demultiplexing the detector output signal.

A calibration assembly is provided which includes a plurality of calibration cells selectively positionable in the radiation path in order to provide an internal calibration standard for two-point calibration of each gas channel. The cells contain one or more of the gas components to be measured at concentrations and pressures predetermined to compensate for the difference in optical path length between the calibration cells and the sample chamber. A technique is provided for characterizing the calibration cells in situ after a conventional calibration, using bottled calibration gas, is performed.

摘要： A gas multiple component analyzer includes an infrared source that passes at least one measuring beam through a sample cell that contains the gas to be analyzed. Three measuring signals are generated in response to the measuring beam, and each is indicative of optical energy from the source transmitted through the sample cell in a respective optical region characterized by a respective optical center wave-length and a respective band pass. The three measuring signals are algebraically combined to automatically determine which of the three end gases is present in the sample cell in the greatest concentration, and the concentration thereof. The disclosed system measures concentration of three separate gases having overlapping absorption spectra.
