Data‐driven model optimization for optically pumped magnetometer sensor arrays [PDF]

Human Brain Mapping, 2019
AbstractOptically pumped magnetometers (OPMs) have reached sensitivity levels that make them viable portable alternatives to traditional superconducting technology for magnetoencephalography (MEG). OPMs do not require cryogenic cooling and can therefore be placed directly on the scalp surface.

Fast Underdetermined DOA Estimation Based on Generalized MRA via Original Covariance Vector Sparse Reconstruction

IEEE Access, 2021
Minimum redundancy array (MRA) has the maximum aperture with continuous difference co-array among various sparse arrays with same number of physical sensors, but it is hard to calculate the sensor position of MRA and realize array design by using MRA. To

Optimization of Planar Interdigitated Microelectrode Array for Enhanced Sensor Responses

Micro, 2023
Immunoassays play a pivotal role in detecting and quantifying specific proteins within biological samples. However, its sensitivity and turnaround time are constrained by the passive diffusion of target molecules towards the sensors.

A Hybrid Global Minimization Scheme for Accurate Source Localization in Sensor Networks [PDF]

, 2011
We consider the localization problem of multiple wideband sources in a multi-path environment by coherently taking into account the attenuation characteristics and the time delays in the reception of the signal.

Optimization of array geometry for direction-of-arrival estimation using a priori information [PDF]

Advances in Radio Science, 2010
This paper focuses on the estimation of the direction-of-arrival (DOA) of signals impinging on a sensor array. A novel method of array geometry optimization is presented that improves the DOA estimation performance compared to the standard uniform linear
