【摘要】In this paper, it presents a new imaging technology that could realize to extent the depth of field and contribute to receive the large iris aperture optical system. The new technology combines lenses assistance and the aberration modulation. Based on the method, we establish a new optical system. Simulation results indicate that the modulation transfer function (MTF) curves of this optical system have consistency feature during different object distances. According to the feature, we can restore ambiguous images to unambiguous ones. Compared with another normal optical system, the experimental results indicate that the new optical system has the large depth of field and large iris aperture features.
