Summary:The invention provides a piece of physical multi-point light attack equipment which serves as equipment for a smart card to realize physical multi-point laser pulse injection. The equipment is used mainly in the smart card information security field and serves as special equipment to detect the testing ability of a smart card product to correspond to laser disturbance. The equipment comprises a laser, optical fibers, optical fiber collimators, a CCD camera and an adjustable platform wherein the laser is connected with the two channels of optical fibers; the far ends of the two channels of optical fibers are connected with the optical fiber collimators respectively so that the light emitted by the laser from the optical fibers are in parallel. In this way, the laser energy loss is reduced; the laser energy is focused; and then, through the CCD camera, the light spots of the two laser beams are observed so as to move them to the target position on the surface of a chip that requires to be analyzed; in doing so,
