Abstract
Fast piezoelectric controlled adaptive optics elements are developed allowing one to design the adaptive optics system with compensation of optical phase aberrations in frequency range exceeding 10 kHz. Adaptive optic elements include: 13-channel deformable mirrors DM-13 with aperture 25 and 30mm, combine device formed with DM-13 attached to the tip/tilt platform, 49-channel deformable mirror PM-49 based on in-pockets piezoelectric multi-pixel actuators. The designs, fabrication and performances of the developed devices are described. The emphasis is made on the experimental investigation of resonance behavior of the devices and influence of the passive damping on the frequency bandwidth.
