Abstract:
An imaging system may include an optical system that forms an image of light irradiated onto a sample in a predetermined focal plane, an imaging element that includes a pixel array in which a plurality of pixels are arranged in a two-dimensional matrix, each of the pixels detecting at least a part of the light of the image of the sample formed in the focal plane, the imaging element obtaining the image of the sample corresponding to the light detected by the pixel array, a spectrum detecting unit arranged to be adjacent to the pixel array, the spectrum detecting unit detecting a spectrum of the light in the focal plane to output spectrum information, and a correcting unit that corrects the image of the sample obtained by the imaging element based on the spectrum information output from the spectrum detecting unit.
Abstract:
A spectral colorimetric apparatus includes a housing which includes a side wall. An outer surface of the side wall is an adjustment surface capable of adjusting a position of a linear sensor by moving while attaching the linear sensor to the adjustment surface. The linear sensor is supported by the side wall of the housing while abutting on the adjustment surface and receives a light beam that is dispersed by a concave surface reflection type diffraction element and passes through an opening portion. The adjustment surface is parallel to a tangential line at a part of a Rowland circle of the concave surface reflection type diffraction element, through which a light beam received by the linear sensor passes.
Abstract:
A compact field spectrograph is described that provides a resolution of 500 or more with no entrance aperture, providing for substantial gain in light throughput, ideal for viewing multiple distant objects with or without telescopic aid, and providing the ability to observe and distinguish a multiplex of objects simultaneously, even if in motion, with minimal or no mechanical tracking required. Spectra may be viewed directly with the unaided eye, or photographed with common consumer cameras.
Abstract:
A microscopic spectrum apparatus for connecting to an image capturing module which is used for converting external image light into electrical signal is disclosed. The microscopic spectrum apparatus includes a microscopic lens module, a spectrum analyzing module and a light beam splitter. The microscopic lens module is used for collecting the external image light to the image capturing module and magnifying the external image. The spectrum analyzing module is arranged at a side of the microscopic lens module. The light beam splitter is arranged between the microscopic lens module and the image capturing module, and is used for directing part of the external image light from the microscopic lens module to the spectrum analyzing module. In addition, a microscopic spectrum apparatus with image capturing capability is also disclosed.
Abstract:
The present disclosure provides for a system and method for analyzing questioned documents. A sample document is illuminated to thereby generate a first plurality of interacted photons. The first plurality of interacted photons are detected at a first detector to thereby generate a digital image. The digital image is analyzed to thereby identify at least one region of interest of the sample document. This region of interest is illuminated to thereby generate a second plurality of interacted photons. This second plurality of interacted photons are passed through a tunable filter and detected at a second detector to thereby generate a hyperspectral image representative of the region of interest. The hyperpsectral image may then be analyzed to evaluate changes to or differentiate different inks present in the sample document. Chemometric techniques such as k-means clustering, PCA, and/or PLSDA may also be applied.
Abstract:
A color luminance meter 1 is provided with a polychrometer 4 as a spectral optical system including a light receiving sensor array 43, a signal processing circuit 5 and an operation control unit 6. The operation control unit 6 carries out calculations to obtain characteristics of a measurement light based on a specified spectral responsitivity, using light reception signals and specified weighting coefficients. The spectral responsitivities of light receiving sensors constructing the light receiving sensor array 43 are selected such that B≧5 nm and A/B lies within a range of 1.5 to 4.0 when A, B denote the half power band width of the spectral responsitivities and a center wavelength interval of the spectral responsitivities. Accordingly, there can be provided a light measuring apparatus capable of maximally suppressing errors to highly precisely measure color luminance values and the like even in a measurement of a light lying in a narrow band such as a monochromatic light.
