LASER TECHNOLOGIES FOR LASER GUIDED ADAPTIVE OPTICS,ystem design issues are addressed, such as laser spot elongation and brightness. The two main families of LGS, based either on Rayleigh or sodium resonant scattering are discussed in terms of performances and of laser technologies required to match requirements. LGS aided AO systems built for astron

OPTICAL AND INFRARED DETECTORS FOR ASTRONOMY,ect, the telescope-instrument act as “spectacles”. The detectors, meanwhile, have the critical role of sensing the light – the detectors are the “eyes” of an observatory. The performance of an astronomical observatory is directly dependent upon the performance of its detector systems.
