Abstract: An optical characteristic measuring apparatus and an optical characteristic measuring method of the invention are an optical characteristic measuring apparatus and method for obtaining a predetermined optical characteristic such as a color value or a total spectral radiation factor of a measurement object. A spectral intensity distribution of predetermined ambient light entering through a measurement opening is measured and stored prior to measurement of the optical characteristic. In measuring the optical characteristic, an optical characteristic in a condition that actually measured ambient light is used as an observation light source is obtained, with use of the stored spectral intensity distribution of ambient light.

Abstract: The optical assemblies disclosed herein advantageously utilize a beamsplitting apparatus in association with either (i) the illumination path or (ii) the collection path of a color measurement instrument. For implementations involving the illumination path, the beamsplitting apparatus may be configured to spectrally divide one or more initial beams of light so as to emit a plurality of resultant beams of light, wherein the optical assembly is configured to illuminate a target using at least a first and a second of the plurality of resultant beams of light. Similarly, for implementation involving the collection path, the beamsplitting apparatus may be configured to spectrally divide light received from a target so as to emit a plurality of resultant beams of light, wherein the optical assembly is configured to detect at least a first and a second of the plurality of resultant beams of light. Advantageously, each of the first and second resultant beams of light is a product of a distinct set of one or more spectral constraints exacted by the beamsplitting apparatus.

Abstract: A color measurement device designed for use at various stages of an industrial process is provided. The device offers enhanced insensitivity to ambient light, measurement depth variations, and/or ambient or environmental temperature variations. The device may be embodied as an LED-based, non-contact color measurement spectrophotometer. Over- illumination in full-spectrum of the target object facilitates effective color measurements over varying depths of view. Collected light is measured at discrete wavelengths across the entire visual spectrum. The hardened, rugged design and packaging of the measurement device allows color measurement to be performed at various stages of industrial processes wherein the device can add value by enabling enhanced detection of color errors.

Abstract: The invention relates to a method and to an electronic circuit for processing signals which as such are indicative of the features or characteristics of the spectral distribution of light which is supplied for spectrometric measurements combined with an LED light source. The problem of the invention is to provide solutions which allow the informative value of spectrometric measurements to be increased. For this purpose, a reference curve for the spectral emission is calculated based on a reference measurement and at least two additional measurements on the same reference, said spectral emission being used as a reference when carrying out measurements of practically any objects. This curve is determined in such a manner that it corresponds to a curve of the spectral emission at a temperature that is outside or far outside the temperature range of the actual temperatures of the LED during the measurements.

Abstract: The invention relates to an illumination device (1) with a number of light emitters, for example LEDs (L1, L2, L3, L4) of individual emission spectra. Sensor units (D1, D2, D3, D4) can produce a vector of measurement signals (S1, S2, S3, S4) that represent the light output of a single active light emitter. Based on a linear relation obtained during a calibration procedure, a characteristic value of the light output of that light emitter (L1, L2, L3, L4) is then calculated from the measurement vector, wherein said characteristic value is based on the coefficients of a decomposition of the individual emission spectrum into basis functions.

Abstract: A color identifying display system having a lighting surface (111, 211, 501, 611) having an alterable apparent surface color, a color capture device (105, 205, 317, 507, 603) to capture a color of an object (109, 203, 305, 503) placed within a detection area, and a processor (113). The lighting surface (111, 211, 501, 611) and the color capture device (105, 205, 317, 507, 603) are coupled to the processor (113). The processor (113) analyzes the captured color to determine a prominent color of the object (109, 203, 305, 503) and to control a color of the lighting surface (111, 211, 501, 611) based on the determined prominent color. The color of the lighting surface (111, 211, 501, 611) may be adjusted to match the prominent color, complement the prominent color, or be analogous to the prominent color.

Abstract: A device for determining the surface topology and associated colour 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 colour 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 colour data and depth data for each point in the array, thereby providing a three-dimensional colour virtual model of the surface of the structure. A corresponding method for determining the surface topology and associated colour of a structure is also provided.

Abstract: A system provides light of selectable spectral characteristic (e.g. a selectable color combination of light), for luminous applications such a signage and indicator lights (10). An optical integrating cavity (11) combines energy of different wavelengths from different sources, typically different colored LEDs. The cavity has a diffusively reflective interior surface (29) and an aperture (17) for allowing emission of combined light. Control of the intensity of emission of the sources sets the amount of each wavelength of light in the combined output and thus determines a spectral characteristic of the light output through the aperture. A deflector (25) shaped like a number, character, letter, or other symbol, may be coupled to a similarly shaped aperture. By combining several such fixtures, it is possible to spell out words and phrases, with selectable color lighting. Disclosed fixture examples use an extruded body member with appropriately located reflective surfaces to form both the cavity and deflector.
