Wavefront sensing for adaptive optics is established as a critical component in building large ground-based telescopes and telescope interferometers for 21st century astronomy. The Phasics SID4 wavefront sensors address many applications in astronomy laboratories and large-scale telescope projects.
The Phasics SID4 and the SID4 HR wavefront sensors are powerful tools for the qualification of laser guide star and associated optical systems. The complete laser qualification (wavefront aberration intensity profiles, laser parameters) is important during the development, implementation, and daily use of the laser guide star in astronomical observatories.
Astronomical observatories rely heavily on complex optical components and setups. To perform at their full capacities those systems need an accurate alignment. SID4 wavefront sensors areused in laboratories during research and development stages and in observatories during the implementation, alignment, and monitoring of optical telescopes.
The combination of high-resolution, nanometric sensitivity and large dynamic-range wavefront measurement make the SID4 HR wavefront sensor the ideal tool for the qualification and development of deformable mirrors. Moreover, the SID4 technology is not sensitive to vibration or environmental instabilities so the qualification can be performed seamlessly.
