Abstract: 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.

Abstract: A printer that incorporates a spectrometry device includes a spectroscope, a distance measurer, and a spectrometry unit. The spectroscope includes a wavelength-selective interference filter on which light from a position of measurement in a medium is incident. The distance measurer measures the distance between the position of measurement and the spectroscope, and the spectrometry unit performs spectrometry at the position of measurement by using the spectroscope and correct a measured value obtained by the spectrometry based on the measured distance.

Abstract: The present invention discloses a co-aperture multi-field of view (FOV) image-spectrum cooperative detection system, and the system includes an infrared optical window, a large FOV two-dimensional scanning mirror, a co-aperture multi-FOV main optical system, a large FOV scanning detector, a staring infrared detector, an infrared non-imaging broadband spectrum measuring unit, a data processing unit, a control unit, and a servo system. Correspondingly, the present invention further provides a method based on the system. The present invention searches a target area by using large FOV scanning, and identifies a target by using medium FOV staring infrared detection, and small FOV fine detection is finally performed on the area to identify the target in combination with spectrum data analysis. The detection sensitivity is higher, and capturing and tracking of a moving target are more precise and stable, thereby solving the technical problems that a conventional remote sensing detection cannot perform research on movement changes of a moving target and a dynamic phenomenon and searching and tracking of a small-scale object is unsuccessful; therefore, the present invention has higher implementability and practical promotion values.

Abstract: Methods and systems for detecting early stage dental caries and decays are provided. In particular, in an embodiment, laser-induced autofluorescence (AF) from multiple excitation wavelengths is obtained and analyzed. Endogenous fluorophores residing in the enamel naturally fluoresce when illuminated by wavelengths ranging from ultraviolet into the visible spectrum. The relative intensities of the AF emission changes between different excitation wavelengths when the enamel changes from healthy to demineralized. By taking a ratio of AF emission spectra integrals between different excitation wavelengths, a standard is created wherein changes in AF ratios within a tooth are quantified and serve as indicators of early stage enamel demineralization. The techniques described herein may be used in conjunction with a scanning fiber endoscope (SFE) to provide a reliable, safe and low-cost means for identifying dental caries or decays.
