Slanted edge method
WebThe slanted-edge method for modulation transfer function (MTF) measurement uses edge target images whose gray values are often affected by noise and other factors, decreasing its accuracy. We first analyze the ill-posedness in the edge spread function (ESF) regression caused by noise. Second, we propose a regularized slanted-edge method to solve this … http://losburns.com/imaging/pbpubs/64WilliamsBurns_EI2014.pdf
