Abstract
An optical heating device includes a heating light source unit having a plurality of planar light source areas in each of which a light source is arranged, and a controller configured to control light output of the light source. The controller includes a storage section that stores temperature distribution characteristic information describing a relation between a relative ratio of the light output of each light source and temperature distribution on a main surface of a tabular test piece, when light from the heating light source unit is irradiated toward the tabular test piece; and an output controller that changes a ratio of the light output based on the temperature distribution characteristic information, in order to bring the temperature distribution of a main surface of an object to be heated obtained when the light is irradiated under a predetermined light output for distribution measurement closer to a desired temperature distribution.
