Book excerpt: 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.
