Hybrid Optical/Digital Architecture for Distortion Invariant Pattern Recognition

Defense Technical Information Center · 1989 · 7 pictures

This 1989 technical report from the Air Force Institute of Technology's School of Engineering, prepared for the Defense Technical Information Center, describes a hybrid optical and digital correlator for recognizing patterns regardless of distortion. Its pictures are grainy spectral and correlation plots, with dense radial spikes, cross-shaped peaks and sparse feature grids, which a designer might use as abstract textures or signal-style graphics.
