Presentation Transcript

  1. consensus on goals: • science competitive edge of LUCIFER MOS • we want a reliable system with low risks • prompt realization of GLAO • upgrade path to on-axis diffraction limited performance • needs to be identified • upgrade path to wide-field, modest Strehl, diffraction limited operations • needs to be identified • consensus on technology: • the lowest risk/affordable choice for GLAO in terms of laser technology • at present is a pulsed Rayleigh system • projection system should be independent of laser technology, be a single • projector for each of the pupils and use simple reflective/lens optics, • allowing both on-axis and off-axis projection schemes • wave front sensors should not require immediate re-design of AGW units: this may require that the wfs are outside the AGW units • identify wfs detectors and suitability of pockel cells • unknowns: • which is the best upgrade path ? • benefit of LGSF to interferometry (given fringe tracking issues) • how fast will a low cost, 3rd generation Na-laser be available commercially? • impact of LGSF on operations & commissioning
