Abstract: Light sensors (1) are used in lighting applications, especially in combination with LEDs, to control and/or adapt the color point of light sources. Costs and/or performance of the light sensor (1) are essential in order to guarantee cost- effective light sources with reproducible color points. This aim is achieved by a light sensor (1) comprising a light diffuser (10), an optical non-transparent housing (11) having at least one window (12), at least one interference filter (13) and at least two photo sensors (14). The light diffuser (10) is arranged in such a way that light from outside the optical non-transparent housing (11) has to pass the light diffuser (10) so as to enter the interior of the optical non-transparent housing (11) via the window (12). The interference filter (13) and the at least two photo sensors (14) are arranged in the interior of the optical non-transparent housing (11), which interference filter (13) is arranged between the window (12) and the at least two photo sensors (14).

Abstract: Device and method for inspecting a polychromatic region, such as a polychromatic pattern, on a moving workpiece. The method includes device includes a solid-state light source, preferably a light emitting diode, adapted to emit light in a range of wavelengths for illuminating the polychromatic region. Photodetectors are positioned relative to the workpiece to intercept light from the light source reflected by the polychromatic region- Each of the photodetectors is adapted to detect reflected light within a corresponding one of a plurality of bands defined within the range of wavelengths. The method includes detecting intensities of the light reflected from the polychromatic region within different wavelength bands in the range of wavelengths and evaluating a ratio of the intensities for comparison with a standard ratio to ascertain a variation in the evaluated ratio.

Abstract: Light (L) from a light source (3) passes through a sample cell (S) and is shone into a spectral unit (13). The spectral unit (13) comprises interference filters (31−39) transmitting optical components having different wavelengths, and photodiodes (41−49) respectively corresponding to the interference filters. A dielectric film constituting an interference filter has a property of comparatively efficiently reflecting optical components other than those having wavelengths permitting transmission. An incident light is divided into a transmission optical component and a reflection optical component at each of the interference filters. A reflection optical component is used as an incident light to a succeeding interference filter to thereby detect optical components of nine types of wavelength.

Abstract: A method and system for effecting an appearance model correction for a display unit, e.g., a CRT, using a polynomial-based algorithm is described. The correction may be effected in real time and is based on gamma values associated with the display. Strong correlations with the CIECAM02 specification are achieved according to the present disclosure. The correction functionality may be implemented using a colorimeter that includes a plurality of sensors/filter systems with non overlappng spectral responses, adequate for providing data capable of translation into standard coordinates system such as, CIE XYZ, CIE L* a* b*, or CIE Luv, as well as non-standard operable coordinate systems. The field of view of the colorimeter is chosen to closely track the response of the human eye using an optical path configured to select and limit the field of view in a manner that is insensitive to placement of the colorimeter on the source image. The optical path from the source image to the sensor is configured to select preferred light rays while rejecting undesirable light rays to maximize the signal/noise ratio. A rearward facing sensor channel is included to simultaneously measure ambient light impinging on the source image and feedback means to provide status and/or change of information.

Abstract: The invention concerns a scanner comprising an integrated photosensitive linear sensor (20) including N photosite parallel lines, with N ≥ 4, preferably, N ≥ 6, and for each photosite line an associated passband optical filter. For each scanning pitch and for each pixel of the analyzed line, it delivers N corresponding quantified partial measurement values, each representing the spectral reflectance of the document collected through the N respective filters. Spectral reconstruction means operate in accordance with an extrapolation method accompanied by learning from reference coloured samples, with a memory (42) storing a knowledge base formed from known spectral reflectance values of said reference samples, and a neuronal network (40) receiving in input N quantified partial values and delivering in output at least one reconstituted quantified value, representing the spectral reflectance of the corresponding pixel of the document.
