Incoherent Optical Heterodyne Fourier Transformer.

Abstract

This invention has significance in the area of automated image analysis for derivation of intelligence information from aerial photography or other image inputs. The Fourier Transform has proven itself to be useful for this purpose and this invention offers a lower noise Fourier Transform than is possible with known analog methods.
