成像光谱偏振仪研究进展

摘要

Imaging spectropolarimeter (ISP) is a type of novel photoelectric sensor which integrated the functions of imaging,spectrometry and polarimetry. In the present paper, the concept of the ISP is introduced, and the advances in ISP at home and abroad in recent years is reviewed. The principles of ISPs based on novel devices, such as acousto-optic tunable filter (AOTF) and liquid crystal tunable filter (LCTF), are illustrated. In addition, the principles of ISPs developed by adding polarized components to the dispersing-type imaging spectrometer, spatially modulated Fourier transform imaging spectrometer, and computer tomography imaging spectrometer are introduced. Moreover, the trends of ISP are discussed too.%成像光谱偏振仪是一类同时具有成像、光谱测量和偏振测量功能的新型光电传感器.介绍了成像光谱偏振仪的原理,对近些年来国内外成像光谱偏振仪的研究进展进行了总结,对基于声光可调谐滤光片、液晶可调谐滤光片等新器件的成像光谱偏振仪和通过在狭缝色散型、空间调制傅里叶变换型和层析型成像光谱仪的光路中添加偏振器件构成的成像光谱偏振仪的原理进行了阐述,并对成像光谱偏振仪的发展趋势进行了展望.
