Call for
Papers
The Astronomical Optics: Design, Manufacture and Test of Space and Ground Systems Conference is dedicated to the engineering and implementation of Astronomical Optical Systems, Instruments, Assemblies and Components for both Spaceborne missions and Ground Observatories. Airborne and Balloon-borne astronomical instrumentation are also included. Current or anticipated future concepts and technologies are appropriate. The scope of papers may include system architecture, methods, materials, special enabling technologies, optical mechanical fabrication as appropriate to topic, and test methods relevant to these missions. Papers may discuss developments in processes, technologies, facilities or equipment used to enable new architectures. Supporting technologies like wavefront sensing and control, payload dynamic disturbance management, active systems, advanced modelling and test beds are appropriate. Papers defining special optical requirements of anticipated new Infrared, Visible, Ultraviolet, X-Ray missions and Exoplanet exploration encouraged. New developments and lessons learned from recent space/ground astronomy related projects are particularly desired.
