Optical imaging system performance estimation is crucial in most related practical engineering applications. The most prevailing tool for performance estimation is MTF, and knife-edge technique is the most popular method to compute MTF. However, traditional knife-edge technique, which was designed for film cameras and other devices that form continuous images, does not consider about the problems of sampling. Focusing on digital image application, this paper proposes a simple method to compute MTF for the purpose of performance estimation of optic simulation system base on traditional knife-edge technique. The method extends traditional knife-edge technique to discuss the problems of sampling, coordinate change and increasing frequency density in digital simulation system. The experiment shows that, in the noise controllable simulation system, digital knife-edge technique could compute MTF rapidly and correctly, and estimate the system performance quantitatively and efficiently.
