On Sampling and Coding for Distributed Acoustic Sensing [PDF]
IEEE Transactions on Information Theory, 2012 The issue of how to efficiently represent the data collected by a network of microphones recording spatio-temporal acoustic wave fields is addressed. Each sensor node in the network samples the sound field, quantizes the samples and transmits the encoded samples to some central unit, which computes an estimate of the original sound field based on the ...

Distributed compressed sensing for photo-acoustic imaging [PDF]
2015 IEEE International Conference on Image Processing (ICIP), 2015 Photo-Acoustic Tomography (PAT) combines ultrasound resolution and penetration with endogenous optical contrast of tissue. Real-time PAT imaging is limited by the number of parallel data acquisition channels and pulse repetition rate of the laser. Typical photoacoustic signals afford sparse representation.
