Abstract

In most adaptive optics systems, there are two elements that control wavefront correction. These are a tip/tilt platform and a deformable mirror. The tip/tilt platform can correct the lower order aberrations like piston, tip and tilt. The deformable mirror can correct the higher order aberrations like defocus, coma, spherical, etc. Currently in this method, two conjugate planes must be created by the two elements. It is also a necessity that these two conjugate planes be identical. This requires more optics and a more complicated alignment process. In this project a deformable mirror is mounted onto a tip/tilt platform resulting in the two correction elements having the same conjugate plane, automatically. This is made possible by the use of a lightweight deformable mirror, as traditional deformable mirrors tend to be quite large and bulky. Results of this experimental project will be presented.
