Abstract: According to an aspect of the present inventive concept there is provided a device for polarization dependent imaging, comprising:
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 translation: 本发明提供一种多焦点光谱测定装置，其能够以高灵敏度同时进行多个样品的测定，并且倍率没有限制。 多焦点光谱测定装置10是将从放置在样品放置部分（样品架13）中的样品S上的多个预定观察区域发出的信号光束引入光谱仪中并由此分散到光谱中的装置，该装置包括 ：多个物镜（物镜聚光部）111，分别位于与多个观察区域分别光学相对的位置; 以及光谱仪输入部分151，它们以这样的方式提供，使得多个物镜111中的每一个具有一个相应的光谱仪输入部分151，用于将穿过相应物镜111的信号光引入光谱仪17中。由于每个物镜111只需要 观察一个观察区域，可以同时增大放大率和数值孔径NA。 因此，在物镜111中聚光的光量相对于从各样品S出射的全部信号光在各观察区域内的比例变高，测定精度也变高。

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: An optical assembly is disclosed including two laterally variable bandpass optical filters stacked at a fixed distance from each other, so that the upstream filter functions as a spatial filter for the downstream filter. The lateral displacement may cause a suppression of the oblique beam when transmission passbands at impinging locations of the oblique beam onto the upstream and downstream filters do not overlap. A photodetector array may be disposed downstream of the downstream filter. The optical assembly may be coupled via a variety of optical conduits or optical fibers for spectroscopic measurements of a flowing sample.

Abstract: Methods and apparatus for combining or separating spectral components by means of a polychromat. A polychromat is employed to combine a plurality of beams, each derived from a separate source, into a single output beam, thereby providing for definition of one or more of the intensity, color, color uniformity, divergence angle, degree of collimation, polarization, focus, or beam waist of the output beam. The combination of sources and polychromat may serve as an enhanced-privacy display and to multiplex signals of multiple spectral components. In other embodiments of the invention, a polychromat serves to disperse spectral components for spectroscopic or de-multiplexing applications.
