Paper Abstract

The current status of the Layer-Oriented approach for the MultiConjugated Adaptive Optics techniques in the Extremely Large Telescopes case is reviewed. This includes a brief analysis of the variations of the concept as they have been conceived up to now, and which could be the developments one should expect (and hope for) in the near future, in the perspective of becoming MCAO for ELTs a reality. Then the concept of Multiple Inverse Bessel Beams, or Pseudo Infinite Guide Stars is given, along with some guidelines about what could be precursor experiments to be performed in order to validate and/or to gain experience in the field.
