Paper Abstract

Modeling of deformable mirror (DM) surfaces is reviewed and two different types of DM models are compared. The first model creates the DM surface through the superposition of an influence function over the extended actuators. The second model uses a two-dimensional cubic spline fit over the extended actuators to create the DM surface. The ability of the predicted DM surface to correct for different spatial frequencies was investigated. It is shown that correctability may vary in both magnitude and shape over the applicable range of frequencies. Results indicate that the bi-cubic spline model is the easiest and fastest to use and it may be extended to incorporate more advanced features.
