Using an X-Ray-Sensitive Vidicon and Remote-Control Stage Mechanism to Obtain Critical Radiographic Alignment of Small Explosive Devices.

摘要

A novel approach for the radiography of small electro-explosive devices to determine the presence or absence of gaps has been developed. Image resolution and part alignment were the main obstacles to be overcome. The required resolution for the inspection was 25 microns. Fine grain x-ray film was found to meet the resolution requirement. The alignment problem was overcome by using an x-ray sensitive vidicon camera and remote control stage mechanism. The input field of view of the camera is 9.5 mm x 12.7 mm. This results in enlargment of 20 to 30 times when viewed on a television monitor. By rotating the electro-explosive device on the remote control stage and observing the monitor, proper alignment for imaging gaps could be obtained. This system can readily detect gaps less than 0.02 mm. (ERA citation 08:037076)
