ABSTRACT:
A hand-held probe system for imaging is described which includes a hand-held probe and a detector assembly connected by a fiber optic cable. The probe includes a hand-portable housing, a detector assembly within the housing and an IR sensor placed on the cold finger of the detector assembly. The probe can include an optical system at a known distance from the sensor and a spacing tube defining the distance between the body and the optical system. The spacing tube ensures that the body whose thermal image is being read is always at, or is very close to, the object plane of the probe. The spacing tube is typically formed of a material having minimal thermal deformation which can minimize stray IR radiation.
