Abstract
Visible and infrared radiation is generated from phosphors within a cold cathode lamp. At least partially transparent media is irradiated with the visible and infrared radiation from the cold cathode lamp. Infrared radiation that passes through the at least partially transparent media is sensed, and an artifact signal is generated from the sensed infrared radiation. The artifact signal corresponds to one or more unwanted artifacts on the at least partially transparent media.
