and analysis means comprising microwave transducers arranged on at least two side walls which are opposite to each other such that the piece of luggage is completely examined by the analysis means when resting on the bottom wall, wherein the analysis means are adjacent an inlet of the cavity such that introduction of the piece of luggage into the cavity causes relative displacement between the piece of luggage and the analysis means and therefore automatic scanning of the piece of luggage by the analysis means. ### Claim 2 (depends on 1) The detection system of claim 1, wherein the trolley comprises casters. ### Claim 3 (depends on 1) The detection system according of claim 1, wherein dimensions of the cavity are at least equal to 460 mm×250 mm×400 mm. ### Claim 4 (depends on 1) The detection system of claim 1, wherein the cavity has a rectangular parallelepiped geometry. ### Claim 5 (depends on 1) The detection system of claim 1, wherein the analysis means comprise microwave transducers and detection means which are distinct from microwave transducers. ### Claim 6 (depends on 1) The detection system of claim 1, wherein the analysis means comprise microwave transducers and at least one of the following means: metal-detecting means, mass-detecting means, presence-detecting means. ### Claim 7 (depends on 1) The detection system of claim 1, wherein the analysis means comprise microwave transducers comprising a plurality of microwave transmitters associated with focusing cones. ### Claim 8 (depends on 1) The detection system of claim 1, wherein the analysis means are arranged around an entire periphery of an opening contour of the cavity. ### Claim 9 (depends on 1) The detection system of claim 1, wherein the analysis means also comprise inductive windings arranged on two opposite side walls which are opposite to each other for detection of metal. ### Claim 10 (depends on 1) The detection system of claim 1, also comprising measuring means configured to measure dimensions of a piece of luggage introduced into the cavity. ### Claim 11 (depends on 10) The detection system of claim 10, further comprising processing means configured to normalize signals from the analysis means as a function of the dimensions of the piece of luggage. ### Claim 12 (depends on 1) The system according to claim 1, wherein dimensions of the cavity are up to 550 mm×300 mm×480 mm. ### Claim 13 A detection method comprises the following steps: introduction of a piece of luggage into a cavity of a trolley, wherein the cavity is defined by side walls and a bottom wall of the trolley such that the cavity fully encloses the piece of luggage, wherein the cavity comprises an open end opposite the bottom wall of the trolley; and placing the piece of luggage onto the bottom wall of the trolley by moving the piece of luggage from the open end of the cavity to the bottom wall of the trolley such that the whole piece of luggage is scanned and analysed by analysis means arranged on at least two opposite side walls of the trolley. ### Claim 14 (depends on 13) The detection method of claim 13, also comprising a step for detection of at least one metal object in the piece of luggage when the piece of luggage is placed on the bottom wall of the trolley.
