Effect of the background clutter on the operating range of infrared polarization imaging system

Design of infrared polarization dual-separation imaging optical system

“…The method of aperture division has high complexity, sensitivity to noise, and weak detection ability. The key to polarized focal plane imaging lies in the manufacturing process of the detector, which is expensive and prone to crosstalk in the optical path [4][5].…”

“…Infrared imaging is the imaging of the radiation energy of the target and background, mainly obtaining the distribution image of small temperature difference between target and background. Compared with visible light imaging, infrared radiation has stronger penetration ability in the atmosphere, so infrared imaging can work at night or in harsh weather, and can identify targets effectively [1] . Based on this, the corresponding infrared camouflage technology has also been increasingly developed, resulting in infrared imaging not playing a better role in some situations.…”
