摘要： The present invention belongs to the field of optical technology, disclosing a quadrilateral common-path time-modulated interferometric spectral imaging device and method. The present invention sets up a moving mirror scanning mechanism in a quadrilateral common path interferometer for generating optical path differences that vary with time, so that the quadrilateral common-path time-modulated interferometric spectral imaging device operates in the staring observation mode. The invention can make the quadrilateral common-path time-modulated interferometric spectral imaging device not only retain the advantages of common optical path spectroscopic technology, but also obtain high spectral resolution.

摘要： A system for non-invasively interrogating an in vivo sample for measurement of analytes comprises a pulse sensor coupled to the in vivo sample for detect a blood pulse of the sample and for generating a corresponding pulse signal, a laser generator for generating a laser radiation having a wavelength, power and diameter, the laser radiation being directed toward the sample to elicit Raman signals, a laser controller adapted to activate the laser generator, a spectrometer situated to receive the Raman signals and to generate analyte spectral data; and a computing device coupled to the pulse sensor, laser controller and spectrometer which is adapted to correlate the spectral data with the pulse signal based on timing data received from the laser controller in order to isolate spectral components from analytes within the blood of the sample from spectral components from analytes arising from non-blood components of the sample.

摘要： Systems for confocal Raman spectroscopy of points of interest or regions of interest with concurrent imaging are disclosed. The imaging may be used for real time selection of points of interest or regions of interest for Raman spectroscopy and to monitor for unwanted motions of a sample while Raman spectra are acquired. Disclosed embodiments apply Reflectance confocal microscopy (RCM) in a confocal Raman spectroscopy system. A single laser may be used as a light source for both RCM and micro-Raman spectroscopy. A Faraday optical isolator may be applied to extract RCM signals for imaging Systems as described herein have example application for ex vivo sample and in vivo skin measurement.

摘要： An optical assembly for an analyzer instrument for analysis of elemental composition of a sample using optical emission spectroscopy includes: an exciter generating an excitation focused at a target position to produce optical emission from the sample; and an optical arrangement including a light collection arrangement transferring the optical emission from the target position to a detector assembly's detector interface. The light collection arrangement includes: an off-axis parabolic light collecting mirror including an aperture, a lens arrangement including converging and diverging axicon lens portions, the lens arrangement positioned so its optical axis is parallel to that of the light collecting mirror and intersects a surface of the light collecting mirror at the aperture, and an off-axis parabolic focusing mirror having its focal point at the detector interface, the optical axis of the lens arrangement being parallel to that of the focusing mirror and intersects the focusing mirror's surface.

摘要： Provided is a measurement device including a spectroscope, a movement mechanism configured to relatively move the spectroscope in one direction, and one or more processors configured to determine whether a measurement position measured by the spectroscope is moved into a color patch, in which the one or more processors cause the spectroscope to execute measurement processing for a plurality of wavelengths set in advance while relatively moving the spectroscope in the one direction, and when at least one of amounts of variation of measured values with respect to each of the plurality of wavelengths obtained in the measurement processing exceeds a first threshold value and then each of the amounts of variation of the measured values of the plurality of wavelengths falls below a second threshold value which is less than or equal to the first threshold value, determine that the measurement position is moved into the color patch.

摘要： A spectral imaging system comprises: a spatial encoder comprising a first light encoding device comprising a first mask for spatial encoding, the first mask being configured with one or more encoding patterns; a spectral encoder comprising: a dispersion arrangement for splitting spatially encoded light from the first light encoding device into a plurality of components; and a second light encoding device comprising a second mask for spectral encoding of the plurality of components, the second mask having one or more encoding patterns; and at least one single-pixel photodetector positioned to measure light that is encoded by the masks. The spatial encoder is operable to spatially encode light by generating a sequence of different patterns or partial patterns of the one or more encoding patterns of the first mask. The spectral encoder is operable to spectrally encode light by relative movement between the dispersion arrangement and the second mask.
