“…Compared to conventional light intensity detection, greatly increasing the information content of remote sensing data, which is of great value for target detection, especially in military applications [7] . In 2019, Rui Zhang et al Proposed a novel hyperspectral polarimetric imaging method based on the super achromatic 1/4-wave slice and AOTF [8] . In 2020, Lixia Gong et al Proposed an aberration-corrected hyperspectral polarimetric image alignment method based on the aberration correction model to correct hyperspectral images with different polarization directions based on the imaging law of hyperspectral polarimetric images, and found that the method has excellent aberration correction effect and high alignment accuracy [9] .…”

By analyzing the principle of polarization detection, a method of identifying unexploded ordnance using polarization spectral information is presented. Then a polarization hyperspectral detection system was designed. Finally, the system was used to conduct detection experiments on mines in the background of cluttered grass at 400-1000nm band. The experimental results indicated that the polarization characteristics of the unexploded ordnance and the natural background were different, and the use of polarization detection technology could well distinguish the unexploded ordnance from the natural background and improve the accuracy of target detection and scene identification, especially in the 450-800 nm band to achieve effective detection and identification of camouflaged targets from the cluttered background.

“…The division-of-time polarization imaging system obtains the intensity images of different polarization states of the target scene in sequence, which has the advantages of a simple system and a medium volume. Moreover, the division-of-time polarization imaging system based on a rotating polarizer is easier to implement and has stronger anti-interference ability than the division-of-time polarization imaging system modulated by liquid crystal devices or acousto-optic devices [4][5][6][7] .…”

In order to effectively improve the contrast of target identification, an acousto-optic tunable filter (AOTF) full-Stokes imaging spectropolarimeter is proposed, which can measure synchronously polarization information with each spectral band in real time. The full-Stokes vectors are obtained by the division-of-aperture polarization imaging system. The spectral bands are selected by RF of the AOTF electrically. Based on this system, a polarization error model is established, and the influence of the key polarization element angle error is analyzed. The results show that the measurement error increases with the increase of the polarization degree. When P = 1 , the influence of the azimuth angle error is greater than the retardance error under the same angle error. The results are helpful to find the variation law of the polarization error and provide a theoretical reference for the design of new types of full-Stokes imaging spectropolarimeters.
