 || '''12.06.2023''' || '''Hans Jürgen Kärcher (Consulting Engineer, Karben)''' || '''Optical Configurations for Extreme Large Telescopes - Viewpoint of a Structural Engineer[[BR]][[BR]]'''The optical layout of large telescopes is defined by the science cases and related science instruments for which the telescope is designated. Design drivers for the optomechanical system of the telescope are the requested wavelength range, magnification, and field of view. The increasing diversity of the science cases leads to increasing expectations for size and quality of its main optical components.[[BR]][[BR]]The lecture gives an overview on optical configurations of large telescopes for different wavelength ranges and throughput – optical, radio, infrared, solar etc., and describes the related challenges for their structural, and mechanical design.[[BR]]'''[[BR]]'''Presentation: German[[BR]]Slides: English[[BR]]Questions: German, English ||

+|| '''19.06.2023''' || '''Hugo Coppejans & Horst Steuer''' || '''Real Time Computing in Adaptive Optics Systems'''[[BR]]Adaptive         Optics is used in astronomy to correct for distortions of the         incoming light into         a telescope. Adaptive         optics system generally consist of three core components: deformable         mirrors, wavefront sensors and real time computers (RTC).         In this talk we will focus on the RTC       in particular         on the one we are currently working on         for         METIS.[[BR]][[BR]]What       is       the task of the RTC in the control loop and what can the RTC       actually       'see'? What are the main data products and which computational       steps       does it have to do to produce them? What is a mode? How fast does       the       RTC have to be and what does 'Real Time' mean? How did we get the       RTC       to be fast enough and what are the main differences between a       central       processing unit (CPU) and a graphics processing unit (GPU)?[[BR]][[BR]]We       will       address these and other questions in a graphic way.[[BR]][[BR]]Presentation: German, English[[BR]]Slides: German, English[[BR]]Questions: German, English ||
