Abstract

Different techniques have been proposed to assess the modulation transfer function (MTF) of sampled imaging systems. Some of these are based on the use of periodic targets made up of thin lines or points. The main potential problem of implementation concerning these methods is the fact that, in specific experiments, it may be difficult to ensure a good balance in intensity between the individual lines or points. An analytical model permitting a first estimation of the actual importance of this problem is presented. The error in the MTF assessment for two generic cameras is then estimated, taking into account the experimental process.
