RTC4AO5 : 5th edition of the RTC4AO workshop
Focus on extreme AO concepts: science requirements pushing forward the limits of current designs, from next generation XAO on VLTs to MCAO on ELTs
AO is an instrumental technique providing, on ground based astronomical telescopes, a significant improvement in resolution (up to a factor 10 for a 8m telescope and 50 for the future 30 to 40m telescopes), especially in the near-infrared by compensating, in real-time, for the effect of atmospheric turbulence. It requires a dedicated realtime control system (RTC) to drive the deformable mirror actuators for the wavefront sensor measurements. When upscaling the current AO control architectures to the future generation of telescopes and instruments, several aspects in the dimensioning and design of the AO RTC become critical, such as handling large and complex data streams or distributing data over the compute cores with real-time capabilities. As such, research in AO real-time control addresses the more general topic of high performance imaging applications and aims at enabling new technologies for transparent low latency pixels data transport from the detector directly to the image processing unit. This could have a significant impact for applications in which real-time image processing is critical including the medical imaging and automotive industries.
