Paper Abstract

Curvature sensing is a non-interferometric wave front sensing method. Its resolution is only limited by the sensor resolution, and it only requires one pixel for each point. In order to understand its applicability it was tested in a controlled laboratory environment. We tried various optical configurations and different data processing methods, such as Projection on convex sets and finite elements. In edition it is presented that a simple silicon wafer, on the back of which porous silicon is etched, can serve as deformable mirror. This is the first report, to our knowledge, of the piezoelectric and piezo-optic response of porous silicon.
