Phase Diversity (PD) is a technique widely used to measure and compensate for Non-Common Path Aberrations (NCPA) in optical systems. Beyond its traditional applications, PD has found further uses in solar astrophysics, where it enhances image quality by processing multiple images to correct residual aberrations. In this work, we introduce a

The 4m class New Robotic Telescope (NRT) is an optical facility designed to revolutionize the rapid follow-up and classification of variable and transient objects. The project is at the stage where key systems are progressing through their detailed design phases, which presents a major engineering challenge for all project partners to manage design

BIFROST, an upcoming instrument for the VLTI, is part of the Asgard Suite, a VLTI visitor instrument. It comprises two spectrograph arms that are optimised for wavelength range of 1- 1.75μm (fed by a fiber that is placed on-axis for fringe tracking/monitoring) and 1-1.3μm (fed by a fiber that can positioned either on-axis or off-axis to observe a
