The Multi Object Optical and Near-infrared Spectrograph (MOONS) instrument is the next generation multi-object spectrograph for the VLT. This powerful instrument will combine for the first time: the large collecting power of the VLT with a high multi

The continuous membrane stiffness of a deformable mirror propagates the deformation of the actuators beyond their neighbors. When phase-retrieval algorithms are used to determine the desired shape of these mirrors, this cross-coupling-also known as i

The Multi-Object Optical and Near-infrared Spectrograph (MOONS) will cover the Very Large Telescope's (VLT) field of view with 1000 fibres. The fibres will be mounted on fibre positioning units (FPU) implemented as two-DOF robot arms to ensure a homo

The purpose of this tutorial is not to describe the theory of model fitting, but to focus on practical aspects and to learn how to work around difficulties. For practice, we use LITpro, a software currently developed within the JMMC 1 research group.

The knowledge of the atmospheric turbulence profile directly above the telescope using the telemetry from wide-field Adaptive Optics (AO) measurements can be extremely useful for the optimization of the correction in the new generation of AO systems.

Multiple sodium laser beacons are a crucial development in multi-conjugate adaptive optics systems that offers wide-field diffraction limited adaptive optics correction to the astronomical community. This correction is strongly dependent on the laser
