ABSTRACT:
An embodiment of an apparatus for enhancing remote infrared (IR) temperature measurement of a low-emissivity sample includes a flexible membrane of a high-emissivity material for converting thermal energy from the sample into IR energy, an enclosed shroud, an IR camera, a light source, and at least one fan. The membrane is coupled to the enclosed shroud at one end of the shroud for supporting the membrane. The shroud includes at least four walls and an end wall opposite the membrane to define an interior space. The end wall includes an imaging window formed therethrough for accommodating the IR camera, which is provided for detecting IR energy radiated from the membrane. The light source is disposed in the interior space and mounted to the shroud for illuminating the membrane. The fan is disposed in an aperture formed in the end wall and is provided for generating an airflow into the interior space onto the membrane to thereby apply a force against the membrane to move the membrane in a direction so that a predetermined surface area of a sample positioned adjacent to the apparatus is contacted by the membrane.
