Abstract

In order to study the polarization imaging characteristics of sea targets in the long-wave infrared spectrum, a set of real-time polarization imaging experimental devices were built using the focal plane long-wave infrared polarization detectors, and experiments were carried out on typical laboratory targets, and the device was used to carry out ship-borne sea surfaces. Long-wave infrared polarization imaging of typical targets. Separate 0°, 45°, 90° and unbiased infrared intensity images from the directly obtained micro-polarization array images, and use the stokes vector method to calculate the polarization degree and polarization angle of the image. The image quality is evaluated through image clarity. The clarity of polarized images is more than 20 times higher than that of infrared images, and the clarity of polarization angle images is 8~10 times higher than that of infrared images. The experimental results show that after the polarization dimension is increased, both intuitive observation and quantitative analysis can find that the clarity of the long-wave infrared polarization image is significantly improved, and the target detection ability is improved.
