 | Stereo imagery has been a goal in optics research since the invention of the stereoscope in 1834. While the market has been inundated with displays of various types, sizes, and formats, no general purpose, easy to use, inexpensive method for the display of imagery in stereo has been developed. The benefits of stereo vision are numerous and quickly become apparent when attempting to perform simple tasks without the aid of ... |

|
| Fundamental properties of neutral networks are discussed and five major models are presented. The emphasis is on the functional interpretation of the describing equations, and includes the nodal activity, learning laws, nonlinear response, stability and overall application areas. Optical implementations by intrinsic nonlinear effects are discussed in detail. Conceptual architectures for the major neural models are presented using optical building blocks for the subsystems. Full concurrent adaptive activity is explicitly ... |

| The report describes the architecture and major components of a hybrid optical/digital correlator which makes use of the reference gray scale for image pattern recognition. The specifics of the electronic/optical design are presented in schematic diagrams. Software listings are included for system test and alignment including a host interface. Operational notes are included. (Author) |

|
| The performance of an incoherent real-time optical correlator with respect to residual tilt and scale misalignment is discussed. The correlator uses CCD video data input streams and produces a real-time output in the form of a standard television video frame. The interlaced fields of the inputs and outputs are discussed and their proper use is described. (Author). |

|
| Document describes an optical system which uses a Wollaston prism in place of a beam splitter to maximize the throughput of the coherent light by taking full advantage of the polarization-dependent characteristics of the basic correlator design. It eliminates one collimating lens and up to two linear polarizer elements, while yielding a compact in-line arrangement and eliminating the need for any folding-path mirrors in order to achieve a small overall ... |
