Abstract

This paper describes a new technique to align and phase the multiple apertures in phased array optical systems. A variety of potential applications exists for this approach, including optical metrology, interferometry, and control systems for next generation astronomical telescopes. The approach as described here uses broadband radiation to accurately measure large optical pathlength differences, and to monitor the performance of a laboratory microprocessor-controlled phasing system. This paper presents theoretical analyses along with results obtained during experimental investigations.
