    A Low Power Cryogenic Shutter Mechanism for Use in Infrared Imagers (2000)
    In:  CASI
    Details
    Publication Date: 2004-12-03
    Description: This paper discusses the requirements, design, operation, and testing of the shutter mechanism for the Infrared Array Camera (IRAC). The shutter moves a mirror panel into or out of the incoming light path transitioning IRAC between data acquisition and calibration modes. The mechanism features a torsion flexure suspension system, two low-power rotary actuators, a balanced shaft, and a variable reluctance position sensor. Each of these items is discussed along with problems encountered during development and the implemented solutions.
