Abstract
Wavefront sensor-less adaptive optics is an important method for correcting wavefront aberration. An appropriate optimization algorithm is crucial to aberration correction. An improved particle swarm optimization (IPSO) is presented which well addresses slow convergence rate and low calculation precision in the standard PSO. In IPSO, mutation strategies are adopted to keep the diversity of population and make particles explore the solution space efficiently. Based on these two algorithms, an adaptive optics system with a 37-element deformable mirror is established. The experimental results show that IPSO is better than SPSO in convergence rate, reconstruction performance and correction effect.
