Optimal node density for two-dimensional sensor arrays [PDF]

2008 5th IEEE Sensor Array and Multichannel Signal Processing Workshop, 2008
The problem of optimal node density for ad hoc sensor networks deployed for making inferences about two dimensional correlated random fields is considered. Using a symmetric first order conditional autoregressive Gauss-Markov random field model, large deviations results are used to characterize the asymptotic per-node information gained from the array.

Optimal design of on‐scalp electromagnetic sensor arrays for brain source localisation [PDF]

Human Brain Mapping, 2021
AbstractOptically pumped magnetometers (OPMs) are quickly widening the scopes of noninvasive neurophysiological imaging. The possibility of placing these magnetic field sensors on the scalp allows not only to acquire signals from people in movement, but also to reduce the distance between the sensors and the brain, with a consequent gain in the signal ...
