[Abstract]:In order to realize the recognition of different mineral compositions, a short-wave infrared imaging spectrometer for ore spectral analysis was developed. Based on this instrument, the image and spectral information of various ores were obtained. The design principle is described, and the imaging quality of the optical design results of the whole system is analyzed. The system was tested by monochromatic collimation method, and the spectral performance parameters such as central wavelength and spectral resolution of each spectral channel were obtained. The results show that the spectral resolution of the instrument is better than 10 nm, which meets the requirement of application. The developed imaging spectrometer is used to test the rock samples and the spectral curves obtained are analyzed. The experimental results show that the instrument has good performance and can accurately judge different ores. The designed short-wave infrared imaging spectrometer has the advantages of high resolution, simple structure, miniaturization, light weight and so on. It is convenient for airborne imaging and beneficial to its application in the field of geological exploration.
