Analysis of multispectral polarization imaging image information based on micro-polarizer array. [PDF]
PLoS OneAs a new detection technology, polarization imaging is of great significance in the field of target detection. At present, polarization imaging technology usually adopts visible light polarization imaging. The technique is difficult to image the target in complex background due to its narrow working spectrum and short detection distance.
