摘　　要：中阶梯光栅光谱仪凭借高光谱分辨率在各领域应用日益广泛,已经成为主要的光谱分析仪器之一。谱图还原技术是中阶梯光栅光谱仪数据处理的核心,通过建立波长和成像位置间的对应关系实现二维图像到一维谱图的快速还原。谱图还原的精度直接决定了中阶梯光栅光谱仪的性能,是仪器开发的重点和难点。鉴于此,本文综述谱图还原技术的发展,将其演变过程归纳为光线追迹、模型化和标定法等3个阶段,重点介绍各阶段谱图还原算法的核心思路与代表方法的原理。最后针对中阶梯光栅光谱仪谱图还原技术,归纳其发展历程、预测其发展趋势、展望其发展方向。The echelle spectrometer is a major spectroscopic instrument with its high spectral resolution in a wide range of applications.The spectral reduction technique is the core of the data processing of the echelle spectrometer,which realizes the rapid reduction of two-dimensional images to one-dimensional spectra by establishing the correspondence between wavelength and imaging position.The performance of the echelle spectrometer is directly determined by the accuracy of spectral reduction,which is the most important point and greatest difficulty in instrument development.In view of this,the development of the spectral reduction technique is reviewed,and its evolution is classified into three stages:ray tracing,modeling,and calibration methods.The core ideas and principles of spectral reduction algorithms in each stage are discussed in detail.Finally,the development history is summarized,the development trend is predicted,and the outlook of the development direction for the echelle spectrometer spectral reduction technology is discussed.
