Demonstration of the Use of Walsh Functions for Multiplexed Imaging

摘要

A proof-of-concept experimental validation of a proposed idea for encodingspatial images using masks with patterns based on a set of orthogonal Walsh functions was conducted. Simple images were encoded via a multiplexing technique, and computer algorithms were developed to decode and to display the results. Photographs of the re-constructed images offer incontestable proof of the validity of this hypothesis for multiplexed imaging. Further research of this technology is expected to lead to full development of an extremely efficient infrared imaging system, with additional applications to passive surveillance, target signature identification, and airborne infrared astrophysics.
