Embodiment Construction

[0026] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] combine figure 1 , the present invention is a real-time multi-spectral tomography imaging device, which mainly includes a laser light path and a prism mask type imaging system. In order to achieve multi-layer chromatography effect more conveniently, such as figure 2 As shown, in actual operation, this device can be installed with an additional row of guide rails. The method of use is to place a reflector on the guide rail, move the base of the reflector to slide on the slide rail, and the laser can pass through multiple faults of the flame or fluorescent material to obtain the spectral information of different faults, and realize the multi-layer detection of the material. chromatography.

[0028] combine image 3 , where the laser optical path includes a pulsed laser, a beam expander, a collimator, and a converging mirror group. ...

Abstract

The invention discloses a real-time multispectral tomography shooting method and device and belongs to the field of computer vision. The method comprises the following specific steps of firstly, generating pulse laser with a certain frequency by a pulse laser, and inducing related components on a chromatographic surface of an object to be analyzed to generate fluorescence; then, under the triggersignal the same as that of the laser, a prism mask type shooting system being used for shooting spectral data of sampling points on the chromatographic surface of the to-be-analyzed object; and finally, reconstructing real-time multispectral chromatography data through a spectral reconstruction algorithm. The device comprises a laser light path and a prism mask type shooting system. The real-timeeffect can be achieved on the basis of spectral chromatography, and therefore the spectral resolution, the spatial resolution and the time resolution can be met at the same time.

Description

technical field [0001] The invention relates to the technical field of multispectral imaging, in particular to a method and device for real-time multispectral tomography shooting. Background technique [0002] Computed tomography in the field of medical diagnosis uses X-rays, uses Wrighten transform or solves algebraic equations to reconstruct the internal fault structure of the photographed material, but cannot reconstruct the spectral information of the fault. In addition, computerized tomography technology has strong hardware requirements, such as requiring multiple emitters and multiple detectors, and the existing computerized tomography technology cannot be combined with spectral technology to capture multi-spectral information of faults. [0003] Laser-induced fluorescence technology has matured as a technology for detecting internal components of flames and fluorescent substances in the past ten years, but what laser-induced fluorescence technology obtains is only the...
