X-ray systems enhance machine vision: Based on amorphous-silicon, CCD, or CMOS sensors, x-ray automated optical imaging systems serve more industries

摘要

Although x-ray imaging systems have been around since the early 1900s, medical diagnostics has been the dominant application. The dangers and complexity of x-ray imaging have kept these systems from a wider variety of applications; however, increased understanding of x-ray sources and safety is quickly pushing x-ray automated optical imaging (AOI) into product-inspection, quality-control, and process-control systems. The unique properties of x-ray radiation are enabling new machine-vision systems that can find obscured defects in solid objects in industries such as electronics, pharmaceuticals, automotive, and food processing.
