Abstract: In some implementations, a device may identify, based on spectroscopic data, a pseudo steady state end point indicating an end of a pseudo steady state associated with the blending process. The device may identify a reference block and a test block from the spectroscopic data based on the pseudo steady state end point. The device may generate a raw detection signal associated with the reference block and a raw detection signal associated with the test block. The device may generate a statistical detection signal based on the raw detection signal associated with the reference block and the raw detection signal associated with the test block. The device may determine whether the blending process has reached a steady state based on the statistical detection signal.

Abstract: A system and a method for setting a fluorescence spectrum measurement system for microscopy is disclosed. Using illuminating light (3) from at least one laser that emits light of one wavelength, a continuous wavelength region is generated. Dyes are stored, with the pertinent excitation and emission spectra, in a database of a computer system (23). For each dye present in the specimen (15), a band of the illuminating light (3) and a band of the detected light (17) are calculated, the excitation and emission spectra read out from the database being employed. Setting of the calculated band in the illuminating light and in the detected band [sic] is performed on the basis of the calculation. Lastly, data acquisition is accomplished with the spectral microscope (100).

Abstract: Disclosed are examples of hyperspectral imager-equipped lighting devices that provide general illumination supplied by artificial or natural light, and that also detect environmental conditions in the environment around the lighting device. The hyperspectral imager detects light within a contiguous spectral band from the environment in the vicinity of the lighting device. In response, the hyperspectral imager generates image data representative of the spectral intensity of one or more subsets of a continuous spectrum of wavelengths of the detected light. A controller may analyze the image data generated by the hyperspectral imager and may initiate action to control operation of the light source or building management products based on an environmental condition detected by the analysis of the generated image data.

The hyperspectral imager detects light within a contiguous data from the environment in the vicinity of the lighting device. In response, the hyperspectral imager generates image data representative of the spectral intensity distribution (e.g. intensities of a continuous range wavelengths in the optical spectrum) of the detected light. A controller may analyze the image data generated by the hyperspectral imager and may initiate action based on, or outputs a report indicating, an environmental condition detected by the analysis of the generated image data.

Abstract: There is provided a photoelectric switch capable of accurately detecting even such a workpiece where a tint changes within the same workpiece, while preventing erroneous detection. The photoelectric switch includes: a light projecting unit; a light receiving unit; a coincidence degree calculating unit for comparing the acquired color information with a reference color to calculate a coincidence degree of both of the color information. When the color information is newly acquired, a detection signal generating unit compares, with a detection determination threshold, the highest coincidence degree of coincidence degrees calculated by respectively comparing the color information newly acquired, with the two or more reference colors, to perform workpiece determination.

Abstract: A method and apparatus for identifying an unknown gas by generating an infrared spectrum of the unknown gas using an infrared spectrophotometer that includes a circular variable interference filter, compressing the infrared spectrum of the unknown gas, and comparing the compressed infrared spectrum of the unknown gas to a library of compressed infrared spectra of reference compounds. After comparison, the compressed spectra that most closely match the unknown gas are decompressed and displayed. Because frequency characteristics of circular variable interference filters vary from filter to filter, information designating these frequency characteristics for the particular filter employed are used in generating the infrared spectrum of the unknown gas.
