Optoelectronic feedback circuit systems for signal processing of high-resolution images for target tracking

Techniques for tracking targets in high-resolution images is an important task. However, computations for processing these types of images can be intensive. With recent advancements in LC devices, DSP, and VLSI, alternate methods are being explored. One of these methods is the use of a hybrid optoelectronic architecture. By combining the parallel nature of optics and the processing capabilities of electronics (DSP/VLSI) these system have the potential for providing fast and compact systems for detecting and tracking targets. A unique feature of these optoelectronic systems is a variety of spatial patterns that can be generated, one is the soliton pattern. This soliton pattern can be used to represent the location of a target within an image. In this paper, simulations of the system show trajectories of solitons indicating tracking of the target.
