Green Flash

AO RTC prototyping and performance assessment

The main goal of the prototyping and validation phase of the Green Flash project is to assess the enabling technologies through prototyping and assemble a full scale demonstrator for an E-ELT first-light AO RTC. As described above, such facility, designed to drive in real-time a large scientific experiment, is composed of a real-time core, processing streaming data from sensors and controlling deformable optics, and a supervisor module, optimizing the control loop by providing updated versions of the control matrix at a regular rate depending on the observing conditions evolution.

The primary objective of this axis of research is to assemble a full functionality prototype for an AO RTC, scalable to the dimensioning of the E-ELT first light instrumentation, including a real-time core and a supervisor module. Architecture choices will be made on the basis of the individual prototyping stages output. (obj. 3.1)

Another objective of this axis of development is to implement a real-time simulator, designed to emulate the AO system I/O with various levels of accuracy, using existing AO sub-systems models. (obj 3.2)

The last objective of this axis of development is to fully characterize the AO RTC prototype performance with several configurations (single and multi-conjugate AO) and propose a strategy for its integration on sky. (obj. 3.3)
