Abstract: 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.

Abstract: 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.

Abstract: 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.
