Imaging detection system with full polarization modulation in highlight environments

This paper proposes a system for modulating and detecting the polarization state of reflected light in a highlight environment. The system can perform light intensity modulation, polarization state modulation, and conversion of any form of polarized light, thereby using the polarization-related principle to suppress or even eliminate the highlighted area of reflected light in imaging. Finally, by combining principal component analysis (PCA) image fusion technology, the imaging effect is greatly improved, the image texture details are increased, the gray value distribution of pixels is changed, and adjustable high-quality imaging detection is achieved. In addition, the theory of full polarization state preparation proposed in this article can also be used to realize the polarization and transformation of various light sources, and change the polarized parameters of the incident light source and make it an ideal light source. Therefore, the method proposed in this paper can not only take into account the modulation and transformation of polarization states but also realize the modulation of light intensity. It also realizes the optimization of imaging quality, which can achieve imaging detection in most complex environments with only one system.
