Abstract

One of the critical components of the AO systems are the WFS detectors that have very challenging requirements of high Quantum Efficiency (QE), and low read noise at high read out speeds. For several years now, ESO has been very active in gathering requirements, planning, and developing detectors and controllers/cameras for the AO systems of the telescope and instruments of the ELT. There cameras are in development: ALICE, LISA and FREDA. For ALICE and LISA, a single camera design approach is being followed with the only difference being the customizable front-ends to support the different type of detector. For the FREDA camera, a different approach is being followed: C-RED One cameras are being procured from First Light Imaging and will be modified by ESO to comply with ELT standards. An update on the progress of this development and measured results of camera test will be provided.
