ABSTRACT:
A laser heating system projects a beam of optical radiation on a region to be heated. A sensor detects changes in temperature of the region by sensing the black body radiation of the heated region. A control circuit then controls the intensity of the beam as a function of the sensed black body radiation. In another embodiment, the beam is moved among the region and the light intensity of the beam is dynamically controlled.
