Optical projection of a thermal target

摘要

A method for generating a thermal target. The method includes generating hot-body thermal radiation from a heated source (10), the thermal radiation emanating from a projection region (12) with a first maximum dimension (DP), and employing an optical arrangement (14) to project at least part of the thermal radiation onto a target region of a surface (16), the target region with a second maximum dimension (DT) greater than the first maximum dimension (DP). <IMAGE>
