Abstract
A scanning radiation sensor (10) for individually determining temperature of a plurality of spots (16') along a scan line (16) on a target (12) responds to inputs to a light marking apparatus (21, 29, 40, 21) to determine which of a plurality of samples produced during a scan cycle are to be selected for averaging (54, 54'). Averages are determined for each scan (54, 54') and then averages for each scan are averaged over multiple scans (56). Both spot target samples (Ts) and reference source samples (Rs) are averaged for improved accuracy, with target samples being converted to temperatures (52) before averaging.
