Abstract

Adaptive Optics improves image quality in telescopes, rapidly moving space objects and laser beam distortion correction through the atmosphere. Many approaches (LGS, GLAO, LTAO) have been demonstrated to address requirements for future telescopes (TMT, ELT). This effort, using Adaptive Wavelets, will reduce complexity and costly hardware, as well as address computation challenges. Wavelet-based phase determination is applied to interferograms and adaptive wavelet echo cancellation will be used to achieve phase conjugate distortion correction.
