Applications of polarimetric imaging in the oil film detection

摘要

In this paper, the applications of polarimetric imaging for rust preventing oil film detection and characterization are discussed. A three-channel polarimetric imaging system is introduced, which can obtained the degree of linear polarization images at one shoot. The experimental results show that the proposed three-channel polarimetric imaging system can identify the oil film on the steel strip quickly and effectively, which is a fast and reliable detection method.
