Adaptive optics

Mitigating atmospheric turbulence is a key aspect of free space optical communication. Delivering clear inbound signals from optical satellites requires dedicated technology and tools to compensate for wavefront distortions caused by the beam traveling through the atmosphere, as well as for precompensation of the pointing systems in uplink signals.

Adaptive optics is a game changer for high bandwidth communications and a required feature for speeds of 1 Gb/s or above. Bertin Alpao, a subsidiary of Bertin Technologies, has been a recognized global leader in adaptive optics since 2008.

Bertin Alpao’s adaptive optic components include high speed deformable mirrors, wavefront sensors, driver electronics and software, both for visible and NIR range.

ALPAO’s deformable mirrors are powered by state-of-the-art electromagnetic actuators, which offer unparalleled precision, speed, and reliability. These advanced actuators employ the magnetic force generated by the interaction between a coil and a magnet to accurately control the movement of the mirror surface. Electromagnetic actuators also offer rapid response times, allowing real-time adjustments to account for dynamic changes in the optical environment such as atmospheric turbulences for instance.

Based on a proprietary electro-magnetic technology, Bertin Alpao’s deformable mirrors range from 37 to 3228 actuators and from 6mm to 150mm pupil diameter. The main features are:

• Superior best flat
• Excellent linearity
• Low hysteresis
• Vacuum compatibility
• Large variety of options (high speed, large stroke, high stability, specific coatings)
• Wide range of accessories
• High dynamic motion
• High number of actuators
• Low power consumption
• Large deformation capacities
• SDK available for C++, Python, Matlab
