    Speckle reduction techniques have been developed as one of the most active research fields in coherent optical information processing, together with the investigations of speckle statistics and coherence theory. The principles of speckle reduction are classified to five categories: 1) control of spatial coherence, 2) control of temporal coherence, 3) spatial sampling, 4) spatial averaging, and 5) ...

    Fourier optics has offered a powerful global information analysis and processing tool to optical domain signals and images and firmly locked its respectable position in the history of optics. The evolution of wavelet theory in the past decade, which has created significant impacts on many areas of information science and engineering, has recently been frequently mentioned in the optics community. ...

    This paper provides a tutorial on the principles of holography, followed by a review of a newly developed 3-D imaging technique in which 3-D optical information of an object cam be extracted by a 2-D optical scan of the object. The technique is called optical scanning holography (OSH). In the context of optical scanning holography, we discuss some of its potential applications such as holographic ... View full abstract»

    The phrase “Concealing Telecommunications Networks” is first introduced as an ultimate philosophical concept in human-to-human or physically evolving “multimedia” communications by employing the same face-to-face mode that is used in natural communications. Then virtual reality (VR) technologies and their current applications are introduced, followed by an introduction of c... View full abstract»

    This article addresses the development of and recent advances in the rapidly growing field of optical pattern recognition. In optical pattern recognition there are two basic approaches; namely, matched filtering and associative memories. The first employs optical correlator architectures and the latter uses optical neural networks (NNs). This paper reviews various types of optical correlators and ... View full abstract»
