Infrared cameras and real-time processing for NDT applications

摘要

In recent years, non-destructive examination using infrared cameras has become increasingly important for industries. The ability to achieve high data rates of modern infrared (IR) Focal Plane Arrays (FPA) require maximum data throughput and a lot of computing power in order to attain high speed infrared imaging. Real-time non-uniformity correction (gain and offset correction for high image quality) must be maintained at high-speed infrared FPA data streams and this will be discussed. The performance of PC-based systems for real-time data acquisition will be described in detail. Some of the infrared systems used in research and development as well as in-line testing systems will be presented. Illustrated by various NDT applications in industry, this paper describes some of the demanding tasks for PC-based concept as well as major resulting benefits.
