Abstract: The invention relates to a multivariate calibration which can be used when the optical system used for that method does not comprise a multi-channel detector such as a CCD sensor or a line array of photodiodes. An optical system without a multi-channel detector doesn't allow to carry out preprocessing steps. Thus there is the need to carry out these preprocessing steps in another way. It is suggested to partially replace the preprocessing step by a measurement of the optical signal, whereby the measurement comprises transmitting or reflecting the optical signal by an optical element, thereby weighing the optical signal by a spectral weighing function. The advantage of the invention is to teach how such an optical system without a bulky and expensive CCD sensor can be used to carry out a multivariate calibration and preprocessing steps.

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.

A device of measuring calorie of an object includes an object holding unit (1) including a table (2) on which an inspection-target object (M) is placed; a light source unit (20) that supplies light in near-infrared regions to irradiate the inspection-target object (M) placed on the turning table (2); a light reception unit (30) that receives light reflected from or transmitted though the object (M); and a control unit (40) that calculates the calorie of the object (M) in accordance with the absorbances of the light received by the light reception unit (30). In the control unit (40), the calorie of object (M) is calculated in accordance with a regression expression and the absorbances of the light received by the light reception unit (30). In this case, the regression expression is preliminarily calculated in the manner that near-infrared rays are irradiated on a calorie known sample object (M), and multiple-regression analyses are performed on second derivative spectra at the absorbances of light reflected from or transmitted though the sample object (M).

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.
