Star-9 is an experimental demonstration of distributed-aperture imaging built at the Lockheed Martin Advanced Technology Center. White light from a scene generator enters an array of nine telescopes and is combined at a focused image plane. Relative

In order for the California Extremely Large Telescope (CELT) to achieve the required optical performance, each of its 1000 primary mirror segments must be positioned relative to adjacent segments with nanometer-level accuracy. This can be accomplishe

One of the requirements for the use of sensitive infrared and scientific detectors is that the entire instrument be cooled to temperatures approaching absolute zero. The cryogenic cooling system for these instalments is usually a large dewar containi

The current trend in the design of large, high performance optical systems is to fabricate the reflecting surfaces from segments, rather than from a single piece of material. The dynamical behavior of a segmented optical system can be analyzed using
