Provided is a single-source low-energy X-
ray back scattering and transmission
human body detection device. An asymmetrical wide fan-shaped angle
X ray source and a fan-shaped front
collimator are installed outside a detection channel and under one side of a control platform. A geometrical structure for transmission measurement and imaging is formed by a transmission
photon beam emitted by the shared
X ray source and a transmission
detector array. A geometrical structure for back scattering measurement and imaging is formed by a back scattering
photon beam emitted by the fan-shaped transmission
photon beam through an object to be measured and a back scattering
detector array. A
radiation shielding layer is arranged between the back scattering
detector and the transmission
X ray beam, a controllable multi-vane light bar is installed at a
ray outlet, and all measurement and control can be finished by one industrial
personal computer. The device utilizes the scanning technology combining back scattering and transmission, and is simple in structure, low in price, high in detection speed, high in sensitivity, small in human tolerant
dose, free of individual privacy
exposure, capable of detecting bombs, explosives, poisons and the like which are hidden in vests and underpants of a
human body and suitable for large public safe sites.
