Abstract:
An absolute transmission accessory for a spectrometer. One example spectrometer system includes a base plate, a light source configured to transmit light, and an interferometer mounted to the base plate. The interferometer receives the light from the light source and output modulated light. The spectrometer system includes a first optical element configured to receive the modulated light and direct the modulated light, and a second optical element configured to receive the modulated light and focus the modulated light to a sample compartment. The spectrometer system includes a detector compartment including one or more detectors, the detector compartment configured to receive light from the sample compartment. The spectrometer system includes a sample holder coupled to the base plate. The modulated light is directed to the sample holder, and light exiting the sample holder is directed through the sample compartment and to the detector compartment via the second optical element.
Abstract:
A system and method of optical spectrum analysis that circumvents the trade-off between resolution and sensitivity by combining two spectral measurements: a first spectrum (102) from first spectral measurement means (240), having high resolution and low sensitivity; and a second spectrum (103) from second spectral measurement means (220), having lower resolution but higher resolution. The input of the of the first spectral measurement means (240) is amplified by an optical amplifier (230), being the effects induced by said amplifier (230) on the first spectrum (102) corrected at processing means (270) by comparison with the second spectrum (103).
Abstract:
Exemplary embodiments of the present disclosure are related to a color target and methods and systems for estimating a spectral reflectance of the color target based on an image of the color target. The color target can include a substrate having a target surface, a sample window formed in the substrate and defining perimeter within which a sample surface is disposed, and one or more filters disposed the sample surface. The one or more filters are configured to cover a first portion of the sample surface, while leaving a second portion of the sample surface uncovered.
Abstract:
The present invention relates to an apparatus for detecting photons according to an atmospheric condition, using a function of adjusting light quantity that can significantly improve reliability of an atmospheric condition analysis result by minimizing noise in a spectrum by maintaining the quantity of incident light uniform within a predetermined range regardless of atmospheric conditions and changes, and to a method of adjusting light quantity. The apparatus for detecting photons in accordance with atmospheric conditions using a function of adjusting light quantity includes: an apparatus case having a light inlet; a light quantity adjuster disposed under the light inlet and adjusting quantity of incident light such that a predetermined quantity of light travels inside; and a controller controlling operation of the light quantity adjuster in accordance with intensity of light detected by the light quantity adjuster.
Abstract:
Provided is an analysis target region setting apparatus that can accurately set an analysis target region, based on an observation image of a sample obtained with an optical microscope and the like irrespective of texture on the sample surface when the analysis target region is set therein. The analysis target region setting apparatus according to the present invention divides the observation image into a plurality of sub-regions based on pixel information on each pixel constituting the observation image. Subsequently, consolidation information on each sub-region is calculated, and two adjacent sub-regions themselves are consolidated based on the consolidation information. According to this, it is possible to divide the observation image into sub-regions having similar pixel information with a disregard of noise attributed to the shape of a surface and the like. A user designates one sub-region from among the sub-regions finally obtained, as the analysis target region.
Abstract:
A modular device includes base and color sensing portions. The color sensing portion has a face, a controlled light source offset from the face to define an interior, the face configured to engage a target surface about a perimeter of the device housing wherein ambient light is restricted from entering the interior. A color sensor receives light reflected from the target surface and generates output signals representative of a surface color. The base portion communicates with the color sensor and a user device having a hosted program which generates a user interface enabling users to provide control input for the color sensor. The program further receives the output signals from the color sensing device and displays a first image of the detected color, and displays a second image of a user-selected color beside the first image. Color data values are further displayed corresponding to the difference between displayed colors.
