Design and simulation of a super-resolving imaging system

The combination system of a pupil filter and an imaging system can achieve super-resolution. Aiming atexploring a method for designing and simulating such a super-resolving system, this paper introducedand discussed the pupil filter design theory at first. Then, based on the knowledge, a new continuouspupil filter and a corresponding imaging system were designed. The designed super-resolving factor Gand Strehl ratio S were 0.7895 and 0.40, respectively. Finally, ZEMAX software was used to simulate thewhole super-resolving system. The simulation results that G equaled to 0.7826 and S equaled to 0.3768,were reasonably smaller than the designed values. The results proved the validity and accuracy of thisdesign and simulation procedure. With this method, it is possible to do risk assessment before productionand reduce cost.
