IR cameras match machine-vision needs: Better performance, lower price, and new interfaces open process-control options

摘要

Infrared (IK) cameras, often referred to as thermal-imaging cameras, have been called "the technology of last resort" for machine-vision applications. The most often cited reason for this is the cost of IR cameras. Until the advent of uncooled IR cameras, these imagers cost USD30,000 and up for a camera with a 160 × 120-pixel focal-plane-array (FPA) sensor.
