Abstract

This Letter presents a novel method for aligning the piston settings for a segmented-aperture imaging system. By sweeping the piston setting for a reference segment, a stack of images can be acquired that encodes information about the relative piston alignment for all segments in the system. We also demonstrate how a matched-filter processing method can be used to estimate the relative piston settings to align the imaging system at its full resolution.
