Abstract: The invention relates to a method and apparatus for determining the color and/or composition of a material. A sample of the material is illuminated with at least three separate illumination bands singly or in combination, said illumination bands collectively substantially spanning at least the visible range. The light reflected or transmitted by the sample is measured with at least four light detector elements responsive to light in wavelength bands which substantially span the visible range when the sample is illuminated. The width of the illumination bands differs in such a manner that the illumination bands are narrowest near the expected fluorescence absorption bands.

Abstract: The present invention provides a combination of first providing a coarse adjustment by varying the emitter (1-1 to 1-n) power and duration of the emitter/detector exposure time (SL-1 to SL-n), and then providing a fine adjustment by storing (13) a correction value for each photodetector element (5). The adjustement for each photodetector corrects not only for the range, but also for the offset, providing two correction values. In a preferred embodiment, the low (offset) and high (offset plus range) voltage reference levels for an analog to digital converter (8) are adjusted and stored for each photodector for each color.

Abstract: The invention concerns a process for checking colour print original copies for correctness and/or accuracy of colouring, alignment, printed image arrangement and the like in the high-speed on-line production of packaging, labelling and comparable mass products. A plurality of production steps are to be performed on different mechanical units whose sequences are controlled by predetermined codes. A plurality of sequentially controlled semiconductor radiation sources (1) of different spectral regions are used. The reflected portion of the radiation focused on the codes of the test sample controls subsequent processing operations via a computer-controlled electronic evaluation system. The semiconductor radiation sources are disposed in a linear and/or monoplanar manner and are controlled sequentially and in a pulsed manner according to their spectral region. The portion of radiation returned by the test sample is projected in the correct position via a receiver lens system onto a CCD receiver and the intensity patterns supplied by the CCD receiver are evaluated by an evaluation system.

Abstract: An apparatus for measuring spectroscopic reflection characteristics from a specific portion of a living organism, e.g. a human body, to detect any pathological changes in said specific portion, such as the development of cancer cells. Rotation of an interference filter (1) causes a change in the relative angle between the filter and light incident thereon, thereby continuously varying the wave length of the light incident upon an object (26). This light is then made to impinge alternately upon the object (26) and a reference reflecting surface (22) by means of a vibrating mirror (4). The light reflected from the object and reference reflecting surface is photo-electrically detected, and the results of detection are processed electrically to obtain spectrographic information from the object.

Abstract: A smartphone is adapted for use as an imaging spectrometer, by synchronized pulsing of different LED light sources as different image frames are captured by the phone's CMOS image sensor. A particular implementation employs the CIE color matching functions, and/or their orthogonally transformed functions, to enable direct chromaticity capture. Various configurations of spectral capture devices are employed to capture spectral images comprised of spectral vectors having multi-dimensions per pixel. These spectral images are processed for use in object identification, classification, and a variety of other applications. Particular applications include produce (e.g., fruit or vegetable) identification.
