Abstract
A hidden object sensor which detects objects behind a surface. The hidden object sensor includes a housing. A capacitive sensor is carried by the housing. The capacitive sensor includes two or more electrodes. The hidden object sensor also includes an inductive sensor disposed in the housing. The inductive sensor surrounds the capacitive sensor in a radial direction such that there is a gap between the inductive sensor and the capacitive sensor.
