(under the class definition) Subject matter having a surface responsive to an infrared or heat pattern and a recording means which may be the responsive surface or a separate means responsive to the surface whose response outlasts its exposure to the pattern.
(1) Note. The pattern referred to above is the thermal or radiation field configuration which is present at the surface of the detector.
(2) Note. The response of the recording means may be visible or invisible (latent). Where the response is latent, additional structure may be included to make it visible, (e.g., develops).
(3) Note. This and the indented subclasses provide for methods associated with the recording apparatus as well as the apparatus itself.
