AbstractIn order to improve the resolution of an imaging system and make the system as simple as possible, the wavefront sensing and the image post-processing using phase diversity are combined to form a new method, i.e., phase diversity hybrid method, in this paper. The performance of this method is simulated for a point source and also for an extended source. An experimental platform is built based on a point source. The experimental results demonstrate that the acceptable results cannot be achieved by using single post-processing for large aberration. The full width half maximum of the light spot descends from 5.1 pixels, 5.1 pixels, and 5.0 pixels which are corrected by adaptive optics to 3.3 pixels, 3.2 pixels, and 3.0 pixels respectively. We can see that the quality of the image processed by phase diversity hybrid method is much better than that restored by post-processing method or corrected by adaptive optics only. It has a great potential application in the filed of high resolution imaging.
