摘要

The present invention relates to a detector device for detection of unauthorised objects or substances, comprising a support base (110) designed to receive at least one foot covered by its shoe, of an individual to be controlled, characterised in that it comprises in combination microwave sender/receiver means (140), measuring means (150) of the width of an element inserted in between the microwave sender/receiver means (140), analysis means of at least one parameter of the transmission time between the microwave sender/receiver means (140) and/or the amplitude of the signal transmitted between the microwave sender/receiver means (140), and standardisation means of the abovementioned analysis relative to a size unit of standard width obtained on the basis of the width-measuring means (150).
