Abstract:

Aerospace applications for terahertz (THz) imaging will be examined in this chapter. The outer skin of the aircraft consists of thin (~ millimeter) sheets of fiber composites that are bonded to honeycombed composites for structural support. During the manufacturing process, quality-assurance inspections could be performed on these thin sheets using a transmissive THz system. A transmissive system can accurately determine the optical path length of the sheet which provides useful information regarding the epoxy homogeneity and regions of delamination. For inspections after the aircraft ...
