Infrared line scan detection is a thermal mapping method particularly suitable to point out defects in non-destructive testing and for process monitoring control. Infrared systems designed for this type of application must show high performances, 24-hour self-operating as well as low cost. Thermo-electrically cooled infrared detector technology makes it possible to reach this goal. The digital signal generated by the optical scanning head is transmitted by means of optical fibers to the processing unit for industrial process control.
