Efficient diffractive optical element (DOE) spatial image separator devices that segment an image and redirect corresponding regions to independent photodetectors are presented. These devices constitute a compact single-element alternative to prism arrays or reflective wedge arrays. DOE's with micro features are fabricated suing conventional microlithography techniques amenable to low-cost production. The system application described is a high-speed RF phase measurement processor for the NRL channelized direction finding receiver. This paper describes the design, fabrication, analysis, and empirical measurements of a 3 segment and 15 segment diffractive spatial image separator. |
