摘要： A micro spectrophotometer is monolithically constructed on a silicon substrate. The spectrophotometer includes a concave grating, which is used for dispersing optical waves as well as focusing reflected light onto a photodiode array sited on a silicon bridge. The silicon bridge is bent 90° from the surface of the silicon substrate in order to orthogonally intersect the output light from the grating. A precision notch is defined in the silicon substrate for coupling to an optical input fiber. Signal processing circuitry is etched on the substrate using conventional CMOS processes for initial processing of information received from the photodiode array.

摘要： An imaging system is disclosed comprising an illuminator which produces illumination of any desired pure wavelength or of any selected mixture of pure wavelengths simultaneously, which illuminates a sample without spatio-spectral artifacts using illumination optics designed for that purpose; imaging optics, which form an image of the sample at a detector or viewing port; and a detector. This enables imaging the complete spectral image cube for a sample by taking sequential images while illuminating with a series of pure wavelengths, with greater ease and economy than by means of tunable filters, interferometers and the like. It further enables imaging while the sample is illuminated with a precisely controlled mixture of illuminant wavelengths, so that the image presented to the detector is a linear superposition of the sample properties at many wavelengths. This enables taking images of a sample' that directly measure the weighted spectral properties such as projection pursuit vectors, principal components, and the like. Data acquisition is enormously simplified, and speed is increased by one to two orders of magnitude over existing techniques. This is of great benefit in pathology, immunohistochemistry, Pap smear analysis, endoscopy, counterfeit detection, quality control, and other areas where one wishes to measure a spectral index of a living or inert sample.

摘要： In an atomic absorption photometer, depending on a fact whether a background correction is carried out or not, a pattern of a pulse lighting of light sources and a timing of sampling a light receiving signal are changed. Namely, at the time of a background correction measurement, one cycle is divided into three periods, that is, a period of lighting HCL, a period of lighting D2L, and an off period, and at the time of a measurement without a background correction, one cycle is divided into the period of lighting HCL and the off period. Accordingly, at the time of the measurement without the background correction, the period of lighting HCL and the off period become longer, and signal-to-noise ratio of the light receiving signal is improved. Accordingly, an absorbance with high accuracy can be calculated.
