Field spectrometer plays a significant role in geological survey, agriculture, vegetation remote sensing, marine remote sensing and environmental monitoring. In the measurement of field spectrometer, the calibration algorithm and correlation processing of spectrometer are the key points and the research hotspots. In this paper, the methods of third-order fitting, linear fitting, polynomial fitting and normalization, respectively, to achieve the field of the spectrometer wavelength calibration and deal with the nonlinear correction algorithm. With the help of the processing ability of big data of the PC, a series of calibration algorithms and related processing functions of wavelength calibration and nonlinear correction spectrometer are designed. Experimental results show that the field in the spectrometer calibration accuracy, accurate to 0.3 nm wavelength measurement, nonlinear fitting precision to 1.029, these algorithms in field spectrometer with actual application, good results were achieved.
How to realize the joint cultivation of excellent engineer for the school and the enterprise is an important task of the project of excellent engineers. In five years of teaching practice, based on the concept of engineering education certification, through target management of school and enterprise, cultural fusion, stage implementation and feedback, excellent engineer education training plan of opto-electronic specialty is being implemented. It standardizes the specialty construction and practice and explores new teaching management mode, which gets the recognition of graduates and enterprises and achieves a win-win situation for school and enterprise.
