Abstract

An X-ray scanner for examining objects moved through an X-ray beam on a conveyor has a detector array disposed at the opposite side of the conveyor from the X-ray source and a pulse generator connected to the motor which drives the conveyor for generating a pulse trail dependent on the speed of the motor, and hence on the speed of the conveyor. The pulse generator is connected to a scanner for the detector array and controls the scan rate dependent upon the conveyor speed. The conveyor speed is controlled such that the quotient of the scan rate and the conveying speed is maintained constant in order to hold the imaging scale constant.
