The Electrostatic Actuated Next Generation Microshutter Arrays

Metadata Updated: May 2, 2019

The field of view required for future missions is much larger than James Webb Space Telescope (JWST). We need to use electrostatic actuation to replace magnetic actuation, so that Next Generation Microshutter arrays (NGMSA) can be scalable to cover large field of view of future telescopes. Our ultimate goal is to develop an extendable electrostatic actuated microshutter array system anticipating the Explorers and other future flight missions in the next two decades. The development of Electrostatic Actuated Next Generation Microshutter Array (EA- NGMSA) as a multi-object field selector for the proposed Explorer Class Missions. This field selector will improve instrument efficiency by up to three orders of magnitude, providing large improvements in performance for optical and UV telescopes, as well as IR systems.We have recently demonstrated electrostatic actuation using electrostatic force to create a concept of an electrically addressable microshutter array. This is a crucial breakthrough which opens the path to a very large focal plane field selectors.  We will further investigate an electrostatic actuation mechanism to reduce actuation voltage and to simplify the actuation process. Electrostatic actuation is critical to enabling MSA actuation and maintaining robust reliable devices. Besides the demonstration of electrostatic actuation of the microshutters, we demonstrated 2-D addressing of the shutters in a NGMSA array. Shutters can be randomly selected open, latch, hold and released close. The development already brought us a ROSES-APRA support (2011-2014 & 2015-2017).
