Abstract

We analyze the imaging performance of synthetic-aperture optical systems (diluted-aperture, and segmented-aperture) using the modulation transfer function. We select a single figure-of-merit, the functional cutoff frequency, over the traditional cutoff frequency, as the most useful one for assessing the optical performance of an instrument for detection of small details. On the basis of this analysis, a simplified layout of the Keck telescope is proposed with an equivalent performance, but employing a smaller number of segments.
