Abstract

A segmented or diluted aperture optical system will undergo phase errors due to errors in the positing of the segments. The errors associated with a segmented primary mirror limit the image quality obtainable with the synthetic aperture telescopes. Here, we study the effects of segmentation errors on image quality considering both the phase angle and amplitude of the OTF. We show that, in these kind telescopes, the phasing and alignment errors among segments reduce the amplitude and distort the phase angle of the OTF.
