成像光谱仪的发展与应用（特邀）

成像光谱仪是一种有效的定量探测工具，得益于其可通过高空间分辨率和高光谱分辨率同时获取探测目标的三维立方体数据的能力，使得成像光谱仪在测绘遥感、目标识别、环境监测与评估、临床影像诊断、过程监控等领域应用极为广泛。文中根据分光原理和分光元件的不同，将成像光谱仪分为四类:滤光型、色散型、干涉型和快照型，在分类的基础上对各种成像光谱仪的主要代表形式和应用进行了回顾和介绍，并对成像光谱仪未来可能存在的发展和应用方向进行了展望。

Development and application of imaging spectrometer (Invited)

Imaging spectrometers, which collect data over three dimension-two spatial and one spectral so that a complete dataset is typically referred to as a datacube, is one of the most powerful and widely used characterization tools in accurate mapping of wide areas remote sensing, object identification and recognition, environment assessment and management, clinical diagnosis imaging and process monitoring and control. According to the different spectral principle and component, imaging spectrometers were divided into four classes as filtering imaging spectrometers, dispersive imaging spectrometers, interferometric imaging spectrometers and snapshot imaging spectrometers. A comprehensive review of main representative forms and applications of various imaging spectrometers on the basis of classification was provided, and the possible development and application of imaging spectrometers in the future were prospected.
