Abstract
A planar sensor array capable of three-dimensional magnetic field sensing is disclosed. The sensor array may be utilized, for example, in connection with security inspections and detection of concealed electronics and contraband. Each sensor pixel may comprise a planar spiral inductor to measure a magnetic field of interest in a first dimension, a first Hall effect sensor to measure the magnetic field of interest in a second dimension, and a second Hall effect sensor to measure the magnetic field of interest in the third dimension.
