【摘要】：为了提高成像光谱仪的光谱定标精度,降低定标过程的复杂度,本文基于单色仪扫描定标法的原理,提出了交互光谱定标的思想,设计了适用于单色仪与成像光谱仪的交互光谱定标系统。分别对单色仪与成像光谱仪进行了光谱定标实验,并对定标数据进行了处理分析。结果显示:单色仪光谱定标精度优于±0.1nm;成像光谱仪的光谱区大于400~800nm,光谱分辨率优于3nm。该交互光谱定标系统避免了对单色仪和成像光谱仪分别定标需要两个探测器的弊端,定标过程中只需切换定标模式,简化了定标过程,能够同时保证单色仪与成像光谱仪的定标精度,具有复杂度低、通用性强、适用范围广及较高的定标精度等优点,可满足实际使用要求。
[Abstract]:In order to improve the spectral calibration accuracy of imaging spectrometer and reduce the complexity of calibration process, based on the principle of monochromator scanning calibration method, the idea of interactive spectral calibration is proposed, and an interactive spectral calibration system suitable for monochromator and imaging spectrometer is designed. The experiment of spectral calibration of monochromator and imaging spectrometer was carried out, and the calibration data were processed and analyzed. The results show that the spectral calibration accuracy of the monochromator is better than that of 0.1nm, and the spectral region of the imaging spectrometer is greater than 400~800nm, and the spectral resolution is better than that of 3nm. The interaction of the spectral calibration system to avoid the monochromator and imaging spectrometer calibration respectively malpractice of the two detectors, switching the calibration mode only need calibration process, simplify the calibration process, and can ensure the monochromator calibration of imaging spectrometer with precision, low complexity, strong versatility and wide range of application and high calibration precision can meet the actual requirements.
