Abstract: A multispectral imaging color measurement system, comprising a dark room (6), a sample platform and an imaging system (1) for photographing objects to be measured; also comprising a controllable illumination system, a filter wheel system, an imaging signal processing system and an electronic control system. The controllable illumination system provides a high spatially-homogeneous illuminated environment for the imaging system (1). The filter wheel system filters the reflected light emitted by the controllable illumination system and reflected by the sample to be measured, and provides a light band with a proper wave length for the imaging system (1) to image. The imaging signal processing system calibrates and performs reflective reconstruction for the image taken by the imaging system (1). The electronic control system controls the operation of each part of the multispectral imaging color measurement system. A method for processing imaging signals of the multispectral imaging color measurement is also proposed. The multispectral imaging color measurement system and the method for processing imaging signals thereof can overcome the defect of inaccuracy of traditional chroma imaging systems and spectrophotometer systems, and provide users in the textile industry with the basic functions of highly accurate color measurement and evaluation.

Abstract: The invention relates to a system and a method for optical measurement of a target, wherein the target is illuminated, either actively illuminated, reflecting ambient light, or self illuminating, and a measurement light beam received from the target or through it is detected. The prior art optical measurement systems generally include mechanical filter wheels and photomultiplier tubes, which cause the equipment to be expensive, large-sized and often not sufficiently accurate and stable. The objective of the invention is achieved with a solution, in which the illuminating light beam and/or measurement light beam is led through a Fabry-Perot interferometer or a set of two or more Fabry-Perot Interferometers, and the Fabry-Perot interferometer or a set of two or more Fabry-Perot Interferometers is controlled into different modes during the measurement of a single target. The invention can be applied in optical measurements where, for example, reflectance, absorption of fluorescence of the target is measured.

Abstract: A dual-mode includes a light source configured to project a structured illumination from which visible light can be filtered. The dual-mode imager also includes a detector configured to capture both the structured illumination and visible light from the scene. A temporal or spatial filter is used to selectively block visible light from one or more portions of the detector while passing the structured illumination to the one or more portions of the detector.

Abstract: The present subject matter relates to methods of high-speed analysis of product samples. Light is directed to a portion of a product under analysis and reflected from or transmitted through the product toward an optical detector. Signals for the detector are compared with reference signals based on a portion of the illuminating light passing through a reference element to determine characteristics of the product under analysis. The products under analysis may be stationary, moved by an inspection point by conveyor or other means, or may be contained within a container, the container including a window portion through which the product illuminating light may pass.
