Addressing System Of Astronomical Micro-Shutter Array For Multi-Body Infrared Spectroscopy

Abstract

This paper presents an automatic control system for electrostatically actuated micro-shutter array for astronomical infrared spectroscopy. A cross-bar like programmable addressing scheme has been developed for the first time to prove all-passive open/close operation of micro shutter elements. Owing to the switching system off the chip, the shutter will not emit thermal noise to the spectroscope imaging device that is vacuum-refrigerated at the liquid nitrogen temperature.
