As the name implies, VT involves the visual observation of the surface of a test object to evaluate the presence of surface discontinuities.  VT inspections may be by Direct Viewing, using line-of sight vision, or may be enhanced with the use of optical instruments such as magnifying glasses, mirrors, borescopes, charge-coupled devices (CCDs) and computer-assisted viewing systems (Remote Viewing).
