Optical Aperture Synthesis Producing High-Resolution Photographs by Incoherent Superposition of Low-Resolution Partial-Frequency Range Component Photographs

  • G. W. Stroke


The long-sought extension to the optical domain of the Ryle (1957) computer-synthesis ‘synthetic-aperture radio telescope’ principle has been obtained by simple photographic synthesis of the ‘high-resolution’ image in a single photograph, exposed successively through sets of small apertures, placed successively to generate the spatial frequency components of the desired large aperture.

The high-resolution “full spatial-frequency range” optical image may be synthesized by superposing in a single plate a suitable set of low-resolution partial frequency-range photographs, obtained separately or simultaneously, with “low-frequency redundancy” supressed by spatial filtering.
