Abstract

The edge method is one of the effective measurement methods based on image analysis for the Modulation Transfer Function of optical systems. By artificially changing the imaging environment, the corresponding changes of the MTF is obtained through the analysis of the object polarization images in the air and at different depth of water. The experimental results show that the MTF of the polarization optical system is stable when the water depth is within a certain range; when the water depth exceeds the threshold, the MTF of the system is drastically reduced. The change rule of MTF also varies with different materials.
