The invention discloses a parallel two-finger mechanical gripper which comprises a driver and two parallel clamping jaws paralleled mutually. The two clamping jaws are connected onto the driver; the driver is used for driving at least one clamping jaw to move; multiple elastic protruding parts are arranged on the opposite inner sides of the two clamping jaws in an array mode; and a cavity is formed in each elastic protruding part, so that the stressed elastic protruding parts can contract inwards when the two clamping jaws clamp an object. The invention further discloses a method for recognizing the types of grabbed objects through the parallel two-finger mechanical gripper. The parallel two-finger mechanical gripper provided by the invention has good stability and adaptability when being used for grabbing objects in different shapes.

The invention discloses a weak X-ray 3D (three-dimensional) imaging method. The used device is mainly composed of a weak X-ray radiation source, a lens module, a detected object module, a detection array module, a signal conditioning module, a host computer and a feedback adjusting module.
