Abstract

In order to achieve simultaneous imaging of the target. According to the principles of polarization and spectral detection, this paper proposes a laser underwater polarization detection system based on the focal plane method, which is mainly composed of imaging lens, laser, analyzer, liquid crystal tunable filter (LCTF), and focal plane polarized camera. The composition can acquire images of multiple polarization angles at the same time, and realize polarization detection of multiple spectral bands by tuning the liquid crystal tuning filter, and then perform polarization polarization fusion processing on the image by extracting polarization spectral information of the target image. The detection of underwater targets yields the expected image. Through underwater detection experiment, the effects of sediment concentration in water on polarization imaging detection are studied. The results show that the sediment concentration in water has a great influence on the polarization image acquisition.
