FIELD: physics.
SUBSTANCE: circuit device for the capacitive detector of hidden objects contains four capacitors, on which are supplied time-dependent voltages, an amplifier, a synchronous demodulator, a comparator, a clock generator. The detector for detecting the frame of hidden elements comprises the above-mentioned circuit arrangement, wherein the capacitor electrodes form capacitor plates which are made in various ways.
EFFECT: increased sensitivity of detection of hidden objects.
