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 at exploring a method for designing and simulating such a super-resolving system, this paper introduced and discussed the pupil filter design theory at first. Then, based on the knowledge, a new continuous pupil filter and a corresponding imaging system were designed. The designed super-resolving factor G and Strehl ratio S were 0.7895 and 0.40, respectively. Finally, ZEMAX software was used to simulate the whole 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 this design and simulation procedure. With this method, it is possible to do risk assessment before production and reduce cost.
