These research results show that hyperspectral remote sensing technology has broad application prospects in the field of geology and mineral resources, but conventional hyperspectral remote sensing images are not suitable for core samples due to their low spatial resolution (30 meters); A core scanning system based on a non-imaging point spectrometer is developed. Typical systems such as the development system of the Nanjing Geological Survey Center and the HyLogger core spectral scanning system in Australia, but because the point spectrum can only space the core at a certain distance Acquisition cannot interpret the continuous and complete spectral information of the core surface, and the spatial resolution of the point spectrum is limited. What is scanned is the mixed spectrum of mineral components, which brings certain difficulties and uncertainties to the interpretation of mineral components.
A high-resolution imaging spectrometer for core samples has not been reported

Abstract
The invention discloses a modularized rock core component spectral imaging scanning system, which comprises a light source unit, a sample unit, and a spectrometer unit; the light source unit emits a light beam with a wide spectral line; the sample unit bears a rock core sample; the rock core sample born on the sample unit are uniformly exposed in the light beam with a wide spectral line emitted by the light source unit; light generated by diffuse reflection of the rock core sample enters the spectrometer unit; and the spectrometer unit performs spectral imaging according to the entered diffuse reflection light. Through the rock core component imaging spectra formed by the combination of image scanning technology with spectral light splitting technology, the modularized rock core component spectral imaging scanning system of embodiments of the invention not only provides the spatial form distribution of the rock core sample, but also provides sample spectral information accurate to pixel points in the imaging field of view, can assist in mineral identification, analysis, result visualization and post-treatment, and provides a new experimental platform for rock core mineral component analysis.
Description
technical field [0001] The invention relates to the field of optics, in particular to a modular rock core component spectral imaging scanning system. Background technique [0002] In geological prospecting work, core drilling is an indispensable and important link, which plays a decisive role in determining the grade and reserves of mineral resources. With the development of mineral resources, the process of deep prospecting has been accelerated, the drilling has become deeper and deeper, and the number of core samples has doubled. Not only the technical requirements for drilling are getting higher and higher, but also the technical requirements for core component analysis are getting higher and higher. [0003] Traditional core component analysis uses image scanners or X-ray core scanning technology to obtain core sample surface image information or three-dimensional images inside the core, but it is still difficult to analyze core samples only based on core sample surface...
