Abstract:
1. A radiation inspection apparatus for object security inspection, comprising: a ray generator configured to emit an x-ray, a collimator configured to collimate the x-ray emitted from the x-ray generator, a detector configured to receive the collimated x-ray collimated by the collimator wherein the ray generator, the collimator and the detector are arranged at predetermined intervals in a horizontal direction, and, wherein the collimated x-ray forms an irradiated area on the detector, the irradiated area being included by an effective detection area of the detector; a driver configured to drive the x-ray generator, the collimator and the detector to rise or fall synchronously and vertically, wherein the driver comprises: the synchronization mechanism comprises a phasemeter coupled to one of the first motor and the second motor, and a phase following meter coupled to the other of the first motor and the second motor, wherein the phase relationship between the phasemeter and the phase following meter is adjusted to achieve a synchronous movement of the first and second driving units.
