SYNTHETIC-APERTURE OPTICS. VOLUME 1. WOODS HOLE SUMMER STUDY, AUGUST 1967
Abstract
The purpose of the present study is to consider the feasibility of increasing optical resolution by what may be termed synthetic-aperture optics. This term is defined here in a very broad sense to include any technique for achieving, with one or more small apertures, the resolution normally associated with a single large aperture. To date, the largest body of experience with aperture synthesis has been in the microwave region of the spectrum, where synthetic-aperture radars and radio-astronomy telescope arrays have been used for a number of years. It should be emphasized that the field of synthetic- aperture optics is very new and relatively unexplored. Volume 1 contains a connected account of the results of the summer study and employs a minimum of mathematics. The various approaches to optical aperture synthesis have been divided into six classes, as follows: Interferometry; Feedback-controlled optics; Imaging with partially filled apertures; Aperture synthesis with coherent illumination; Object restoration beyond the diffraction limit; and Miscellaneous aperture synthesis techniques.
