Abstract :
This paper reports on the measurement and reconstruction using two algorithms of an adaptive tilt mirror´s reflected wavefront using a Shack-Hartmann wavefront sensor. The combined wavefront corrector consists of a deformable mirror mounted onto a fast steering platform. Reconstruction of the wavefront was performed using finite difference and finite element reconstructors for comparison. The Shack Hartmann wavefront sensor and the two types of software reconstructors provide a visualization of the mirror´s surface
