Single-arm Design Method for Multiple Aperture Imaging Telescopes

Open Access Open Access

Abstract

The performance of wide-field multiple-aperture imaging systems is dominated by easily understood, low- order errors. Each aperture produces an individual image, each pair of apertures produces a set of fringes under a diffraction envelope, and the system bandwidth produces a coherence envelope. For wide-field imaging, each of these elements must be coincident in the image plane as the field angle changes. The above physical errors will appear in system wave fans as pistons, tilts, and defocus errors. Each type of error can be corrected by the method listed in the table below.
