Two-Dimensional Direct Electronic Fourier Transform (DEFT) Devices: Analysis, Fabrication, and Evaluation.

Abstract

This document serves as the interim report for the period 10 June 1976 to 9 June 1977 on the project entitled, Direct Electronic Fourier Transforms of Images, funded by the U.S. Army Night Vision Laboratory. It was demonstrated that films possess a large surface acoustic wave (SAW)-related conductivity modulation proportional to the square of the SAW-associated electric field in the LiNb03 substrate, as expected. Thus the modulation provided the pseudo-beam steering effect on which the two-dimensional Fourier transformation property rests.
