DETECTOR OF CAMERA ELEMENTS WITH REGULATION SCHEME

摘要

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.;18 cl, 32 dwg
