Abstract: A device measures a spectral distribution with respect to each of a plurality of color charts, sets default values to band specification data, and computes a camera output signal based on spectral sensitivity of the multiband camera and spectral feature of light from each of the plurality of charts. The device computes a candidate value of a spectral estimation parameter from the measured spectral distribution of each color chart and the computed camera output signal. The device successively varies the band specification data from the default values to make an evaluation function approach a target value, determines a spectral estimation parameter corresponding to the band specification data when the evaluation function reaches the target value. The evaluation function is defined to correlate the measured spectral distribution of each color chart to a spectral estimation value computed from the candidate value of the spectral estimation parameter and the camera output signal.

Abstract: An optical filter includes a first variable wavelength bandpass filter that extracts light of a first wavelength band and has first and second spectral bands and a second variable wavelength bandpass filter that extracts light of a second wavelength band adjacent to the first wavelength band and has third and fourth spectral bands. Part of the period during which the light of the first spectral band is extracted overlaps with the period during which the light of the third spectral band is extracted, and part of the period during which the light of the second spectral band is extracted overlaps with the period during which the light of the fourth spectral band is extracted.

Abstract: A device for determining the surface topology and associated color of a structure, such as a teeth segment, includes a scanner for providing depth data for points along a two-dimensional array substantially orthogonal to the depth direction, and an image acquisition means for providing color data for each of the points of the array, while the spatial disposition of the device with respect to the structure is maintained substantially unchanged. A processor combines the color data and depth data for each point in the array, thereby providing a three-dimensional color virtual model of the surface of the structure. A corresponding method for determining the surface topology and associate color of a structure is also provided.

Abstract: A system and method for detecting analytes using a conformal filter. A conformal filter, which may comprise a tunable filter, is configured to filter interacted photons conforming to a spectral shape correlated with an analyte of interest. Conformal filter configurations may he selected by consulting a modified look-up table associated with an analyte.

Abstract: Spectrometric apparatus that include an array of detector elements and exhibits a number of capabilities is disclosed. The elements can be responsive to incident radiation to produce an output signal that includes information from the incident radiation. A spectrally selective element can be located in an optical path between the radiation source and the array, with an analysis module responsive to the output signal operative to analyze spatial distribution of spectral information received by the array. The apparatus can also correct for differences in intensity and spectral variability for spectral image signals and/or compare the spectral image signals with a pattern in spatial-spectral coordinate space. Detector elements can be responsive to scattering, and spatial information in their output can be analyzed.

Abstract: Proposed is a light sensor (1), comprising at least one wavelength selective photo-detector (10), a lens (20) and an aperture (30).The wavelength selective photo-detector allows detecting light within a predefined wavelength range falling on the sensor. The lens project light on the photo-detector and the aperture defines a field of view of the light sensor. The photo-detector (10), the lens (20), and the aperture (30) are arranged in a telecentric configuration. Advantageously, this allows light to impinge on the wavelength selective photo-detector within a predefined range of angles irrespective of the direction of the light incident on the aperture, thus removing the angle dependent response of the wavelength selective photo-detector.
