Deformable mirror for efficient correction of large aberrations

摘要

The present invention relates to a deformable mirror, specifically a gimbaled deformable mirror for use with wavefront sensors, which mirror separates the tilt correction from the higher order modes (e.g. defocus, spherical, astigmatism, and coma at higher order aberrations, up to the limits of a particular mirror design) in order to use all of the available mirror deformation stroke for correcting the higher order modes. The separation is done by placing the deformable mirror in a gimbaled structure, so that the deformable mirror can be tilted in two independent, orthogonal axes.
