Abstract

High resolution observation of celestial objects has always been the goal of optical interferometry. In this paper, we concentrated on two aspects of image reconstruction for Fizeau interferometric telescope. 1. The influence of piston error on imaging quality was studied, which provides a basis for the technical specifications of telescopes. 2. We proposed to use speckle imaging technology in interferometric telescopes, this method can reduce the effect of atmospheric turbulence on the resolution. In summary, a method combining denoising algorithm and speckle imaging technology is used to suppress noise, remove turbulence and reconstruct high-resolution images of real objects. The simulation results show that speckle imaging technology is also applicable to the interferometric telescope, and got good image reconstruction effect. The research results can be further extended to other mosaic telescopes.
