(under the class definition) Subject matter comprising (1) a source of invisible radiation of the class type and (2) a
means (i.e., recording detector) sensitive to the radiation from the source, or secondary radiation generated by the source, whose response (visible or latent; i.e., invisible) is effectively permanent (or "semi-permanent" in the sense that it can be reversed and the device re-used for subsequent recordings), and, where an image of an object is desired, (3) the object in the radiation path from the source to the detector.
(1) Note. The radiation path of (3) supra will include the path of radiation deflected from the object if the recording detector is to respond to deflected radiation or the path of transmitted radiation if the recording detector is to respond to radiation that passes through the object without substantial deflection.
(2) Note. Fluorescent and phosphorescent detectors whose response to invisible radiation of the class type may outlast their exposure to such radiation are excluded from this subclass and the indented subclasses as not being effectively permanent. See search notes below.
