DESIGN OPTIMIZATION OF A LIGHTWEIGHT SECONDARY MIRROR ASSEMBLY FOR A 1-M CLASS GROUND TELESCOPE FOR SATELLITE LASER RANGING

Design optimization of a lightweight secondary mirror assembly for a 1-m class ground telescope for satellite laser ranging

Large-sized ground telescopes have been developed to meet the high demands for opto-mechanical imaging systems in space and military applications.In line with these advancements, we developed a 1-m class ground telescope for astronomical imaging and satellite laser ranging (SLR).In a ground telescope, mirror deflection is mainly induced by gravity
