Abstract: A system and method for color measurements or other spectral measurements of a material are provided. An illuminating device generates light for illuminating a sample of material. A detector detects light that has interacted with the sample and provides a measurement of the light that has interacted with the sample. A controller adjusts a duty cycle of the illuminating device to control the illumination of the sample. The measurement could be used by an analyzer to determine a spectral characteristic of the sample (such as a color of the sample). The determination of the spectral characteristic could be done without using any measurement of light that has not interacted with the sample. One or multiple light emitting diodes (LEDs) could be used to illuminate the sample, and the duty cycle of individual LEDs or groups of LEDs could be adjusted.

Abstract: A light fixture, using one or more solid state light emitting elements utilizes a diffusely reflect chamber to provide a virtual source of uniform output light, at an aperture or at a downstream optical processing element of the system. Systems disclosed herein also include a detector, which detects electromagnetic energy from the area intended to be illuminated by the system, of a wavelength absent from a spectrum of the combined light system output. A system controller is responsive to the signal from the detector. The controller typically may control one or more aspects of operation of the solid state light emitter(s), such as system ON-OFF state or system output intensity or color. Examples are also discussed that use the detection signal for other purposes, e.g. to capture data that may be carried on electromagnetic energy of the wavelength sensed by the detector.

Abstract: To generate a reference database for a particular sensor in a multiple LED spectrophotometric system with a reduced number of test measurements taken from training samples, a first set of reflectance reference measurements are generated from a test target on to a reference sensor from a plurality of different LED emissions. A first spectral reconstruction reference matrix is computed by performing an operational characterization of the reference sensor from the first set of reflectance reference measurements. A second set of reflectance reference measurements from the test target is generated from a second subject sensor whose operation is to be personalized by the objective reference database. The second set of reflectance reference measurements are less in number than the first set. A second reconstruction matrix is computed by performing an operational characterization of the subject sensor from the second set of measurements. The second reconstruction matrix is adjusted by relating the second set of reflectance measurements to a set of corresponding reflectance measurements of the reference sensor, whereby the adjusting of the second matrix comprises computing an optimal solution spectral reconstruction matrix for the second sensor. The reference database is generated from the optimal solution spectral reconstruction matrix.

The colorimeter measures a sample under a calibrated light source, receives inputs to detectors, and determines CIE tristimulus values of the same sample as they would occur under a reference light source. The colorimeter includes a calibrated light source and a single silicon chip that includes three or more detectors. Each detector is permanently coated by a different mix of dyes or other colorants that form a wavelength-selective filter. A single silicon chip embodies all the detectors and electronics, with each detector coated over by deposited filter layers.
