Abstract

A nine-aperture, wide-field Fizeau imaging telescope has been built at the Lockheed–Martin Advanced Technology Center. The telescope consists of nine, 125   mm diameter collector telescopes coherently phased and combined to form a diffraction-limited image with a resolution that is consistent with the 610   mm diameter of the telescope. The phased field of view of the array is 1   μrad . The measured rms wavefront error is 0.08 waves rms at 635 nm. The telescope is actively controlled to correct for tilt and phasing errors. The control sensing technique is the method known as phase diversity, which extracts wavefront information from a pair of focused and defocused images. The optical design of the telescope and typical performance results are described.
