In his talk,           Matt Preston           will give an overview on the Large Area Sensor CMOS and new           technology           developments at Teledyne and their applications in astronomy.[[BR]][[BR]]Presentation: English[[BR]]Slides: English[[BR]]Questions: English ||
 || '''20.10.2025''' || '''Jens Helmling (CAHA)''' || '''50 years of technological evolution at the Calar Alto Observatory[[BR]]'''[[BR]]Technology develops incredibly fast. For years, Calar Alto received most of its technology from the MPIA, initially with photoplanes, even in the IR range, then came Retincon, CCDs, IR detectors, and increasingly CMOS. Today, many developments are carried out on site by Calar Alto staff, from new telescope control systems to improvements in efficiency, for example in Carmenes' radial velocity measurements.  In this talk, Jens Helmling will take us on a journey of technological evolution along the last 50 years of the observatory.[[BR]][[BR]]Presentation: German[[BR]][https://svn.mpia.de/trac/att/attachment/wiki/WikiStart/CAHA_50.pdf Slides: English][[BR]]Questions: !English/German ||

This talk presents a major instrumentation             effort on Maunakea to reduce residual wavefront error and             improve contrast through two facility adaptive optics             upgrades: the Keck II High-Order Advanced Keck Adaptive             Optics (HAKA) upgrade and Subaru’s next-generation facility             AO (AO3k). Both upgrades center on higher-order ALPAO             deformable mirrors with enhanced wavefront sensing and             real-time control. In this presentation, laboratory             activities are highlighted, particularly test-bench setup,             modular lab control software, and results from the             site-acceptance testing of the higher-order DM at Keck.             Together, these improvements target higher Strehl ratios and             deeper raw contrast at small angular separations, enabling             sharper direct spectroscopy of older, cooler exoplanets and             revealing scattered-light structure in moderately extincted,             planet-forming disks. The presentation concludes with             selected science outcomes from the upgraded Subaru AO             system.[[BR]][[BR]]Presentation: English[[BR]]Slides: English[[BR]]Questions: English ||
