Abstract: Focusing a generated radiation signal on a detector is effected by a curvilinear surface. The radiation beam signal from the reflected surface is collimated or focused on the detector. Light scattered, Raman scattered, fluorescence, chemiluminescence, phosphorescence radiation signals from particles as a result of a chemical procedure or reaction is enhanced through this focusing technique. The enhanced signal which is detected is subsequently measured through different detection techniques.

a detector comprising light sensitive elements;
a plurality of light propagating units, each comprising a polarization splitter having a receiving end for receiving incident light, and comprising a first and a second waveguide.
The first and second waveguides comprise a first and second portion of the receiving end. The first and second waveguides comprise a first and second distributing end, separate from each other. The polarization splitter is configured to propagate received light to the distributing ends. Each of the portions has an elongated shape such that propagation of light in the waveguides is dependent on the light's linear polarization. The elongated shapes are angled with respect to each other, such that the waveguides are configured to propagate different linear polarization directions.
Each light propagating unit is arranged such that light at the first and second distributing ends is output towards a first and second light sensitive element, respectively.

Abstract: Provided is a multifocal spectrometric device capable of simultaneously performing a measurement of a plurality of sample with high sensitivity, with no restriction on the magnification. A multifocal spectrometric device 10 is a device in which beams of signal light emitted from a plurality of predetermined observation areas on samples S placed in a sample placement section (sample holder 13) are introduced into a spectrograph and thereby dispersed into spectra, the device including: a plurality of objective lenses (objective light-condensing sections) 111 individually located at positions which respectively and optically face the plurality of observation areas; and spectrograph input sections 151 provided in such a manner that each of the plurality of objective lenses 111 has one corresponding spectrograph input section 151, for introducing signal light passing through the corresponding objective lenses 111 into the spectrograph 17. Since each objective lens 111 only needs to observe one observation area, both the magnification and the numerical aperture NA can be simultaneously increased. Consequently, the proportion of the amount of light collected with the objective lens 111 to the entire amount of signal light emitted from the sample S within each observation area becomes high, and the measurement accuracy also becomes high.

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.
