Visual testing (VT), involves the visual observation of the surface of a test object to evaluate the presence of surface discontinuities. With sufficient lighting and access, visual techniques provide simple, rapid methods of testing. Close visual testing (CVT) refers to viewing directly with the eye, with or without magnification, while remote visual testing (CVT) refers to the use of optical devices such as borescopes and fiberscopes.
