摘要： The invention relates to a measuring arrangement for detecting an absolute reflection spectrum of a sample in a process for producing the sample. It comprises a light source for generating measurement light, a homogenizer for generating a uniform spatial illuminance distribution of the measurement light; a movable reflector and a receiver for collecting the measurement light reflected from the sample and/or the reflector. According to the invention, the reflector both for a reference measurement and for a sample measurement is positioned in an observation beam path and arranged on the same side of the sample as the light source in order to feed the reflected measurement light to the receiver.

摘要： To provide a microspectroscope that can perform a wide range mapping measurement with high sensitivity, at high speed, and with high wavelength resolution.The Raman spectroscope comprises: a unit for linearly irradiating excitation light; a movable stage for a sample; an objective lens for focusing Raman light from the linear irradiation region; an incident slit provided at the imaging position of Raman light; a spectrometer for diffusing the passing light; a CCD detector for detecting Raman spectral image; and a control device for controlling the mapping measurement by synchronizing the movable stage and the CCD detector. The control device controls the movable stage to move in the direction orthogonal to the longitudinal direction of the linear irradiation light and obtain one average spectrum. At the same time, the control device is configured to perform the cycle of the CCD detector While the stage is moving to obtain one average spectrum of the moving region of the linear irradiation region in one light detection cycle.

摘要： A multi-mode imaging spectrometer that incorporates two orthogonally positioned entrance slits and is configurable between a first mode in which the system produces images of relatively wide spatial coverage with moderate spectral resolution, using a first one of the two slits, and a second mode in which the system produces images of a smaller spatial area with fine spectral resolution, using the other one of the two slits.

摘要： Methods are provided to identify spatially and spectrally multiplexed probes in a biological environment. Such probes are identified by the ordering and color of fluorophores of the probes. The devices and methods provided facilitate determination of the locations and colors of such fluorophores, such that a probe can be identified. In some embodiments, probes are identified by applying light from a target environment to a spatial light modulator that can be used to control the direction and magnitude of chromatic dispersion of the detected light; multiple images of the target, corresponding to multiple different spatial light modulator settings, can be deconvolved and used to determine the colors and locations of fluorophores. In some embodiments, light from a region of the target can be simultaneously imaged spatially and spectrally. Correlations between the spatial and spectral images over time can be used to determine the color of fluorophores in the target.

摘要： The present subject matter relates to methods of high-speed analysis of product samples. Light is directed to a portion of a product under analysis and reflected from or transmitted through the product toward an optical detector. Signals for the detector are compared with reference signals based on a portion of the illuminating light passing through a reference element to determine characteristics of the product under analysis. The products under analysis may be stationary, moved by an inspection point by conveyor or other means, or may be contained within a container, the container including a window portion through which the product illuminating light may pass.

The spectrophotometer is characterized in that the storage unit (34) stores a threshold for detecting the entry of external light into the photodetector (12), and that the control unit (31c) detects the entry of the external light into the photodetector (12) on the basis of the output intensity signals in the light blocking periods, and the threshold.

摘要： A downhole fluid analysis tool has a tool housing and a fluid analysis device. The tool housing is deployable downhole and has at least one flow passage for a fluid sample. The fluid analysis device is disposed in the tool housing relative to the flow passage. Inside the device, one or more sources generate a combined input electromagnetic signal across a spectrum of wavelengths, and a routing assembly routes generated signals into the reference and measurement signals. At least one wheel having a plurality of filters is rotated to selectively interpose one or more of the filters in the paths of the reference and measurement signals.
