Two-dimensional spatial light modulars: a tutorial

Article Abstract:

An SLM (spatial light modulator) is a real-time device that can be reconfigured and that can modify the amplitude or intensity, phase, or polarization of an optical wavefront as a function of position across the wavefront. Two-dimensional SLMs serve as input transducers and perform basic processing operations on optical wavefronts, making them an important part of optical information processing systems. SLMs functions include analog multiplication and addition, signal conversion, nonlinear operations, and short-term storage. The major classification categories are determined by the optical modulation mechanism, the modulation variable, the addressing mode, the detection mechanism for optically-addressed SLMs, and the addressing mechanism for electrically-addressed SLMs. New optical modulation materials and novel device configurations must be found before significant improvements in SLM performance are possible.

Tutorial on higher-order statistics (spectra) in signal processing and system theory: theoretical results and some applications

Article Abstract:

Higher-order statistics to a wide range of signal processing and system theory problems are presented in this cumulative collection and tutorial. Useful theoretical results are compiled here, along with descriptions of the applications of higher-order statistics to the identification of nonminimum phase channels from just noisy output measurements; over 20 new methods are summarized. The paper demonstrates the utility of higher-order statistics to practical problems. Included in the tutorial are definitions of cumulants, impulse response formulas, multichannel formulas, harmonic processes, estimates of cumulants, applications, and derivations and relationships. Basically, the paper is a collection of a large number of relatively new theoretical results for higher-order statistics.
