Paper Abstract

Modulation transfer function (MTF) of optical systems is often derived by taking Fourier transform (FT) of a measured line spread function (LSF). During MTF measurement process, the measurement accuracy of MTF will decrease as a result when LSF computed is not veracity. Based on the model constructed using the variance information of knife-edge and skew of the knife-edge, this paper presents a new method to improve the accuracy of measurement of MTF. The results showed that the new method can improve the accuracy of MTF to 0.01.
