Wavelet methods in multi-conjugate adaptive optics

Multi-Conjugate Adaptive Optics: a PSF study

A model of a multi-conjugate adaptive optics system is used to estimate the performance of such a system in the infrared and in the visible. It is shown that the corrected field of view can be largely increased, using a Gemini-like system. Residual anisoplanatism is studied, when different natural guide star schemes are used. In any case the field of view is significantly increased. A scheme to...

A Wave Optics Propagation Code for Multi-Conjugate Adaptive Optics

We describe the purpose and sample results of a wave optics propagation simulation developed to study multi-conjugate adaptive optics for 4-10 m class telescopes. This code was developed to assess the impact of di raction e ects and a variety of implementation error sources upon the performance of the Gemini-South MCAO system. These e ects include: Hartmann sensing with extended and elongated l...

Multi –Conjugate Adaptive Optics Test-bed for horizontal propagation

Our program for the upgrade of the Naval Prototype Optical Interferometer with large telescopes and adaptive optics has produced a test-bed for the in system evaluation and testing of our MEMs adaptive optics components and system performances. We have already reported in recent publications the basic characteristics of the test-bed. In order to improve the capabilities of such laboratory set-u...
