This paper provides the first public disclosure of an optical technology which makes possible important new opportunities for the construction of very large telescopes. This technology, developed by Kaman Corporation in an Independent Research and Development program extending over the past several years, is generically known as PAMELAN, an acronym for Phased Array Mirror, Extendable Large Aperture. Kaman's patented PAMELA, approach leads directly to the ability to build rugged, diffraction-limited optical telescopes or beam expanders for ground-based or orbital deployment that have unprecedentedly low weight. In addition, the entire optical system will be fault-tolerant, leading to large expected savings in overall system cost and complexity. These attributes make PAMELATM a prime candidate technology to benefit both civilian and military optical systems in such areas as laser applications, imaging, remote sensing, and communications. PAMELATM will also have broad applicability to the needs of astronomy.
