In this paper we report about the preliminary design of the Real Time Computer (RTC) for the MAORY@ELT Multi-Conjugate Adaptive Optics module for the ESO Extremely Large Telescope. The ELT MCAO module provides high sky coverage, large field, diffraction limited correction in the near infrared. It relies on the use of a constellation of six Laser Guide Stars (LGS) and up to three Natural Guide...
The fabrication and characterization of a Silicon based photo-controlled deformable mirror (PCDM) for spatial light modulation and wavefront control is reported. The device is a 1-inch clear aperture membrane mirror (5 μm thick nitrocellulose membrane) coupled with a 1-inch monolithic non-pixelated Silicon photoconductive slab. A transparent ITO electrode is deposited on one side of the...
