Abstract: A transmission Raman spectroscopy apparatus has a light source for generating a light profile on a sample, a photodetector having at least one photodetector element, collection optics arranged to collect Raman scattered light transmitted through the sample and direct the Raman light onto the at least one photodetector element and a support for supporting the sample. The support and light source are arranged such that the light profile can be moved relative to the sample in order that the at least one photodetector element receives Raman scattered light generated for different locations of the light profile on the sample.

Abstract: A lens scanning mode hyperspectral imaging system and a rotor unmanned aerial vehicle include: an imaging lens, an imaging spectrometer and a surface array detector arranged in sequence and coaxial to a main optic axis, wherein the imaging spectrometer and the surface array detector are connected and mounted to each other; wherein the lens scanning mode hyperspectral imaging system further includes: a driving device for driving the imaging lens to translate relative to a plane where a slit of the imaging spectrometer is. The hyperspectral imaging system of the present invention overcomes the technical bias in the prior art that the imaging lens must be fixed, and the present invention provides relative motion between the target object and the imaging spectrometer by the lens scanning mode for imaging, which solves the image distortion problem of conventional hyperspectral imaging system using a slit scanning mode or a scanning mode.

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: Aspects of a monochromator are described herein. In one embodiment, the monochromator includes a light source that provides light, a diffraction grating including a first diffraction grating and a second diffraction grating, a grating drive motor that rotates the diffraction grating to provide dispersed wavelengths of light, a detector that detects a portion of the dispersed wavelengths of light, and processing circuitry that controls a grating drive motor to regulate an angular velocity of the grating based on an angular orientation of the diffraction grating. By using a diffraction grating having multiple, different dispersive surfaces, measurements of relatively high precision and quality may be taken throughout a wider spectral range. In another aspect, the processing circuitry controls a sample drive motor to vary an angle of incidence of the dispersed wavelengths of light onto a sample for evaluation.

Abstract: A spectral microscopy device includes a spectral detecting unit including a light source capable of controlling an output wavelength, a microscope section having an observation area illuminated with light output from the light source, and a signal detector that detects light from the observation area as spectral data; a moving unit configured to move the observation area; and a controller that performs a control operation to allow the spectral detecting unit and the moving unit to move in response to each other. The spectral microscopy device is controlled so that switching between different measurement conditions based on the number of measurement points is performed at an observation area movement time in which the observation area is moved by the moving unit and measurement is performed and at a an observation area movement stoppage time in which the observation area is fixed and measurement is performed, and spectral data is detected.
