A compressive spectral and polarization imager based on a pixelized polarizer and colored patterned detector is presented. The proposed imager captures several dispersed compressive projections with spectral and polarization coding. Stokes parameter images at several wavelengths are reconstructed directly from 2D projections. Employing a pixelized polarizer and colored patterned detector enables compressive sensing over spatial, spectral, and polarization domains, reducing the total number of measurements. Compressive sensing codes are specially designed to enhance the peak signal-to-noise ratio in the reconstructed images. Experiments validate the architecture and reconstruction algorithms.
提出了一种基于像素化偏振器和彩色图案探测器的压缩光谱与偏振成像仪。该成像仪通过光谱和偏振编码捕获多个分散的压缩投影。几个波长处的斯托克斯参数图像可直接从二维投影重建。采用像素化偏振器和彩色图案探测器可在空间、光谱和偏振域实现压缩感知,减少测量总数。压缩感知编码经过专门设计,以提高重建图像中的峰值信噪比。实验验证了该架构和重建算法。
