The Dynamic Components of a Phased Array Imaging System

Abstract

The phased array telescope imager or Multipurpose Multiple Telescope Testbed (MMTT) contains several important dynamic components. These components are used to maintain the critical optical geometries required to coherently combine multiple telescope apertures. Here we describe the dynamic components that manipulate the optical geometry. A more complete optical and controls description can be found in the references. The experiment contains two dynamic systems. One is used to maintain beam tilt, beam piston, and pupil geometry while the other allows the sensor system to examine the entire field of view.
