Why a deformable mirror ? Adaptive imaging Aberration compensation Precision light manipulation Source: Elliot Scientific Source: NASA Source: TU WIen Technology, limited to priviliged institutions- what about others?

How does it work? Piezoelectric diaphragm Segmented electrodes Curvature proportional to applied voltages 3 DoF : tip, tilt, defocus

The fabrication Piezo buzzer Coat with paint Mark the electrodes Etch the mounting arms Solder wires Glue the mirror

The electronics 10 TI integrated circuits The heart is a quad bipolar DAC, amplified up to ±50 V Ultra low-noise and high voltage switching power supplies Microprocessor unit with onboard trajectory processing

The complete system
