title = "Knife-edge method for measuring the optical transfer matrix of polarization imaging systems",
abstract = "As a method to analyze the performance of optical polarization imaging systems, Optical Transfer Matrix (OTM) enjoys some distinct advantages, such as more objective, more reliable, applicable to both small and large aberration optical systems. The OTM describes the spatial frequency transfer characteristic of the system for each Stokes parameter propagating from the object plane to the image plane. In this paper, we give a spatial frequency analysis of a polarization imaging system and use knife-edge method to characterize the OTM of polarization imaging systems. In the experiment, we detect the Stokes Parameters in each state under the illumination of six typical polarized states of spatially incoherent light, and we use the experimental results to calculate the OTM. As compared with the optical grating method, the knife-edge method can measure the OTM of polarization imaging system in real time. The performance of polarization imaging systems can be evaluated by analyzing the image with OTM. This provides technical support for the subsequent research on OTM.",
