Abstract: A device and method for identifying solid and liquid materials use near-infrared transmission spectroscopy combined with multivariate calibration methods for analysis of the spectral data. Near-infrared transmission spectroscopy is employed within either the 700-1100 nm or the 900-1700 nm wavelength range to identify solid or liquid materials and determine whether they match specific known materials. Uses include identifying solid (including powdered) and liquid materials with a fast measurement cycle time of about 2 to 15 seconds and with a method that requires no sample preparation, as well as quantitative analysis to determine the concentration of one or more chemical components in a solid or liquid sample that consists of a mixture of components. A primary application of such analysis includes detection of counterfeit drug tablets, capsules and liquid medications.

Abstract: In a measuring probe 40, a measuring beam is diffused by a first diffusion plate 19, and when received by a plurality of light-receiving sensors 13B, 14B, 15B via a plurality of interference filters 13A, 14A, 15B, the measuring beam is made incident on the interference filters 13A, 14A, 15B via second diffusion plates 13C, 14C, 15C. Those interference filters 13A, 14A, 15B are formed such that transmittance characteristics corresponding to a measurement parameter are obtained correspondingly to intensity distribution conditions for an angle of incidence of light incident on the interference filters 13A, 14A, 15B. Therefore, the measuring probe 40 can reduce the effect of displacement of the transmission characteristic caused by the angle of incidence, while using the interference filters 13A, 14A, 15B.

Abstract: A hyperspectral camera includes light mixing chambers projected onto an imaging sensor. The projection of each chamber is slightly larger than a sensor pixel. The chambers are placed as a linear array in a slit plane or as a two dimensional matrix in front of the imaging sensor. The mixed light from each chamber is depicted by several sensor pixels. The sensor outputs information used to form an overdetermined equation set. The set is solved and optimized for the solution giving the lowest overall error or the best fit. The solution of the equation set combined with the optimization is the intensity values of the chambers constituting imaginary pixels being calculated. These imaginary pixels form the output of an improved hyperspectral camera system, which has significantly lower optical errors like keystone and point spread function variation for different wavelengths.

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.
