MORFEO is a post-focal adaptive optics module that forms part of the first light instrument suite for Extreme Large Telescope (ELT). The project now in Final Design Phase. In this paper, we report status project.
MAORY is a post-focal adaptive optics module that forms part of the first light instrument suite for ELT. The main function to relay beam from ELT focal plane client while compensating effects atmospheric turbulence and other disturbances affecting wavefront scientific sources interest.
Pyramid Wavefront Sensors are sensitive to piston. Here we present the preliminary work, which uses a spatial light modulator as digital pyramid wavefront sensor detect piston from segmented phase screen.
MORFEO (formerly known as MAORY) is a post-focal adaptive optics module that forms part of the first light instrument suite for Extreme Large Telescope (ELT). The project passed Preliminary Design Review in two stages April and July 2021 now entering Final Phase. In this paper we report status project.
MAORY is the adaptive optics module for ELT providing two gravity invariant ports with same optical quality different client instruments. It enable high angular resolution observations in near infrared over a large field of view (~1 arcmin2 ) by real time compensation wavefront distortions due to atmospheric turbulence. Wavefront sensing performed laser and natural guide stars while sensor an deformable mirror which works together telescope's tip tilt mirrors M4 M5 respectively.
MORFEO (Multi-conjugate adaptive Optics Relay For ELT Observations, formerly MAORY), the MCAO system for ELT, will provide diffraction-limited optical quality to large field camera MICADO. has officially passed Preliminary Design Review and it is entering final design phase. We present current status of project, with a focus on optics aspects expected milestones during next project
The ESO ELT is expected to come into operation in 2025 and it will be the largest optical telescope world. Its performance relies heavily on Adaptive Optics (AO) systems including integrated adaptive M4 mirror post focus MAORY system featuring an additional two mirrors. A verification unit (aka 'Test Unit' (TU) conceived test functionality prior its installation telescope. TU requirements solution emulate natural laser guide stars, atmospheric turbulence partial correction by are described.
The next generation of large telescopes will use segmented primary mirrors. These segments must be co-aligned to a small fraction the optical wavelength. Any difference in piston, tip, and tilt cause degradation final image. In this paper, we investigate some methods detect, particular, discontinuous phase steps at edges between adjoining segments. For experiment, GHOST bench developed by ESO Adaptive Optics Systems group. This includes Spatial Light Modulator (SLM) which generates known...
