提出了一种高光谱Mueller矩阵成像(HMMI)方法,实现了空间、光谱和Mueller矩阵图像的同步一体化获取。详细讨论了高光谱Mueller矩阵成像的原理以及双折射干涉器剪切干涉成像过程,对偏振态发生器/偏振态分析器进行了联合优化设计,给出了系统的定标方法。为验证仪器的性能,在实验室对目标进行光谱Mueller矩阵成像,证明了利用所提方法快速获取光谱图像和Mueller矩阵图像的可行性。所提方法具有光谱分辨率高、偏振调制快等优点,为光谱Mueller矩阵成像的发展提供了一种新的思路。
Abstract
A hyperspectral Mueller matrix imaging (HMMI) method to capture spatial, spectral and Mueller matrix images at the same time is proposed. The principle of hyperspectral Mueller matrix imaging and the shear interference imaging process of birefringent interferometer are discussed in detail. The joint optimization design of polarization state generator and polarization state analyzer as well as the calibration method of this system is shown. In order to verify the performance of the instrument, the spectral Mueller matrix imaging of the target in the laboratory proves the feasibility of HMMI in quickly acquiring spectral images and Mueller matrix images. Because of its high spectral resolution and fast polarization modulation, it provides a new idea for the development of spectral Mueller matrix imaging.
