It is pointed out that the motivation for going from monolithic to synthetic aperture optical telescopes has traditionally hinged on requirements in fabrication, deployment, and structures (moment of inertia). The potential for reducing weight and cost has also been a motivating factor. Usually it is assumed that some sacrifice is being made in optical performance. In the present investigation, the special case of ranging telescopes is considered, and it is shown that while there is a slight degradation in the diffraction-limited optical performances at long ranges, the optical performance of a properly phased synthetic aperture system at ranges from close to moderate is significantly improved over a monolithic telescope of equivalent aperture. A monolithic ranging telescope is discussed, and a family of normalized characteristic design curves is developed.
