الوصف: | This report summarizes the results of a 3-year program of research on the physics and technology needed to develop high-performance optical memory and optical processing systems based on the concept called the stimulated photon echo (SPE). The research goals were investigation, demonstration, and improvement of signal strength and fidelity, architectures and algorithms, and materials properties for optical storage and in-memory processing. Key accomplishments were (1) development and demonstration of efficient algorithms for threshold discrimination and bit-error-rate reduction in retrieved binary images with large in-frame and frame-to-frame intensity variations; (2) demonstration and characterization of information storage in Erbium-doped crystals using 1.5-micron diode lasers compatible with fiber optic communications; (3) demonstration of improved phase-encoding schemes for in-memory temporal correlation of 1.5-micron pulse trains; (4) development of concepts for high-performance radar applications based on SPE optical memory for time-delay control of the transmitter array and in-memory image processing of the return signals; and (5) hosting the AFOSR Contractors' Meeting, "Optoelectronic Information Processing." |
