| Abstract: | Compared with the technique of adaptive optics,image restoration from wave-front sensing does not adopt complicated fabrication and control technology of deformable mirror.It is a low cost and high performance-price ratio method that can overcome atmosphere turbulence and get optimal image.By the method,images can be deconvolved according to instantaneous optical transfer function and a set of short-exposure degraded images.Measurement errors of the wave-front sensors and wave-front reconstruction errors ar... |
