Bilinear solution to the phase diversity problem for extended objects based on the Born approximation

Andrei, Raluca M; Fraanje, Rufus; Verhaegen, Michel; Korkiakoski, Visa; Keller, Christoph U; Doelman, Neik


We propose a new approach for the joint estimation of aberration parameters and unknown object from diversity images with applications in imaging systems with extended objects as astronomical ground-based observations or solar telescopes. The motivation behind our idea is to decrease the computational complexity of the conventional phase diversity (PD) algorithm and avoid the convergence to local minima due to the use of nonlinear estimation algorithms. Our approach is able to give a good...[Show more]
