Optical Correlation Studies. Continuation of LENS Program.
Abstract
The present program was provided information that is vital in the determination of the role that optical processing will play in acoustic data gathering systems. The program plan was designed to investigate whether a special purpose optical processor can truly interface with and augment the performance of digital processing equipment. The major accomplishments of this study were: (1) The development of an optical processing algorithm that would accept narrowbanded complex samples and form an ambiguity surface. (2) An optical system was designed and constructed to implement this algorithm. (3) The optical processor was tested by recording simulated acoustic data on film and using these masks as inputs. (4) Experiments were performed on this test bed that provided information on accuracy and detectability of the optical output. (5) Direct comparisons of the optically generated surfaces to surfaces calculated digitally with the same data were made. (6) It was ascertained that these optical techniques would be amenable to real-time implementation if spatial light modulators were substituted for the film media.
