偏振视觉

Traditional vision techniques have been widely used in various fields. However, when facing complex environments and non-cooperative targets, the limited information obtained renders traditional vision techniques ineffective in detecting and recognizing targets. As a basic physical property of light, polarization, alongside intensity, wavelength, and phase, can reflect the vibrational characteristics of emitted or reflected light and characterize multiple aspects of objects. Therefore, polarization information can effectively distinguish targets from backgrounds and maintain information validity in adverse environments. Researchers have introduced polarization information into the vision technique and obtained a solution to the imaging problem in complex scenes, namely polarization vision. Polarization vision was first discovered in some animals, and further research on polarization vision has revealed its imaging advantages over traditional vision in complex scenes. This review focuses on the development of polarization vision, polarization imaging devices, and their applications. We also look ahead to the future development direction of polarization vision and related technologies.
