ABSTRACT:
A method for generating a thermal target. The method includes generating hot-body thermal radiation from a heated source, the thermal radiation emanating from a projection region with a first maximum dimension, and employing an optical arrangement to project at least part of the thermal radiation onto a target region of a surface, the target region with a second maximum dimension greater than the first maximum dimension.
