Coherence sensing and signal processing
Frontiers in Optics 2004/Laser Science XXII/Diffractive Optics and Micro-Optics/Optical Fabrication and Testing, 2004Coherence measurements enable sources of radiation to be distinguished, rather than just measure power as in conventional incoherent imaging. Instruments that sample the partially coherent field are discussed with numerical algorithms to separate the fields from sources and achieve infinite depth-of-field imaging.

Signaling causal coherence relations
Discourse Studies, 2013Signaling of relations is an open question in rhetorical structure theory (RST). Discourse markers are the unmistakable signals of a relation. However, it may be argued that all relations – and not only those involving discourse markers – are signaled in some way.

Detection of coherent and noncoherent signals via the stochastic signals model
[Proceedings] ICASSP 91: 1991 International Conference on Acoustics, Speech, and Signal Processing, 1991A novel method for detection of coherent and noncoherent signals, based on the application of Rissanen's minimum description length principle for model selection to the stochastic signals model, is presented. In this method, the detection and localization are done simultaneously, with the location estimator coinciding with the maximum likelihood ...
