A compact Fourier-transform imaging spectropolarimeter covering a 450-1000 nm spectral range is presented. The sensor, which is based on two birefringent retarders and a Wollaston interferometer, offers significant advantages over previous implementations. Specifically, with no internal moving parts, electrically controllable or micro polarization components, the full wavelength-dependent state of polarization, spectral and spatial information of a scene can be acquired simultaneously. Outdoor measurements of several cars and plants demonstrate the sensor's potential for color measurement, target identification, and agriculture monitoring applications.
本文介绍了一种紧凑的傅里叶变换成像光谱偏振仪,其光谱范围覆盖450 - 1000纳米。该传感器基于两个双折射延迟器和一个沃拉斯顿干涉仪,与以前的实现方式相比具有显著优势。具体而言,由于没有内部移动部件、电可控或微偏振组件,能够同时获取场景中与波长相关的完整偏振态、光谱和空间信息。对多辆汽车和植物进行的户外测量证明了该传感器在颜色测量、目标识别和农业监测应用方面的潜力。
