    摘要: The present disclosure provides a method of providing a hyperspectral image of a scene comprising a point (p). The method comprises providing an imaging device (10, 10') comprising a two-dimensional image sensing unit (12, 13, 14) having a spectral characteristic, which varies along at least one direction in a plane parallel with an image sensor (13), acquiring a first two-dimensional image (11) of the scene, the first image comprising the point (p), wherein the spectral content of the scene varies along the direction as a consequence of the varying spectral characteristic of the image sensing unit (12, 13, 14), moving the imaging device (10, 10') and the scene relative to each other, acquiring a second two-dimensional image (I2) of the scene, the second image comprising the point (p), wherein the spectral content of the scene varies along the direction as a consequence of the varying spectral characteristic of the image sensing unit (12, 13, 14), identifying the point (p) in the second image (I2) as a second pixel at a position (x2, y2) depicting the point (p), providing a spectral vector (S(p)) of the point, and providing an updated spectral vector (S'(p)) of the point based on an applicability vector (A(p)) of the point (p), the spectral vector (S(p)) of the point, a spectral value (z2(p)) of the second pixel and an applicability vector (B(p)) of the second pixel.

    摘要: A color detector includes a light source, a photodiode, and a filter tuned to only allow light of a specific color to pass through to the photodiode. When the light reaches the photodiode, the photodiode outputs a current that indicates that the color is present in the light. The filter may include a pair of partially reflective layers consisting of a reflective metal, such as silver. To prevent the metal from oxidizing or reacting with the environment, the partially reflective layers may be coated with a protective layer, such as aluminum nitride. The color detector may further include a color enhancing layer. Finally, the color detector may include a capping layer. Accordingly, the color detector provided herein allows for the filter to use metals for partially reflective layers that would normally oxidize, as well as detect light of a specific spectrum of wavelengths.

The detector (110) comprises: —at least one transfer device (120), wherein the transfer device (120) comprises at least two different focal lengths (140) in response to at least one incident light beam (136); —at least two longitudinal optical sensors (132), wherein each longitudinal optical sensor (132) has at least one sensor region (146), wherein each longitudinal optical sensor (132) is designed to generate at least one longitudinal sensor signal in a manner dependent on an illumination of the sensor region (146) by the light beam (136), wherein the longitudinal sensor signal, given the same total power of the illumination, is dependent on a beam cross-section of the light beam (136) in the sensor region (146), wherein each longitudinal optical sensor (132) exhibits a spectral sensitivity in response to the light beam (136) in a manner that two different longitudinal optical sensors (132) differ with regard to their spectral sensitivity; wherein each optical longitudinal sensor (132) is located at a focal point (138) of the transfer device (120) related to the spectral sensitivity of the respective longitudinal optical sensor (132); and —at least one evaluation device (150), wherein the evaluation device (150) is designed to generate at least one item of information on a longitudinal position and/or at least one item of information on a color of the object (112) by evaluating the longitudinal sensor signal of each longitudinal optical sensor (132). Thereby, a simple and, still, efficient detector for an accurate determining of a position and/or a color of at least one object in space is provided.

    摘要: A colorimeter with multiple sensings of light to provide higher accuracy measurements of the primaries of a human-standard observer based color space is provided. This color space (target color space) must have the characteristic of two chromaticity coordinates and an achromatic primary like CIELAB, CIELUV or xyY in CIE 1931. The calibration of the device includes training with a set of calibration illuminants. Two sets of calibration-factors are determined. The first set of calibration factors yields intensity of primaries optimized with respect to chromaticity, the second set yields the optimized intensity of the achromatic primary. The combination of these sets of calibration factors enable the colorimeter to deliver values of that light with respect to three primaries of a human-standard-observer-based color space optimized with respect to chromaticity and the achromatic primary.
