Abstract
In this paper, we present two original concepts of deformable mirrors to compensate for first orders optical aberrations with a minimum number of actuators: one optical mode is generated with one actuator. The Variable O_-Axis parabola (VOALA) concept is a 3-actuators, 3-modes system able to generate independently Focus, Astigmatism3 and Coma3. The Correcting Optimized Mirror with a Single Actuator (COMSA) is a 1-actuator system able to generate a given combination of optical aberrations. The limited number of degrees of freedom of such systems makes them easy to set up and monitor, which is a significant advantage, notably for space use.
