When it comes to remote visual inspection, there has been an improvement in overall imaging quality as a result of fully digital data streams and improved optical and illumination technology, which, in turn, has led to a greater probability of flaw detection and improved inspection productivity.
Inspection, and specifically nondestructive testing (NDT) or examination, is a vital technology for the operation of any industrial plant and in the manufacture of any product. Inspection is carried out to assess the functional integrity of offshore oilrigs, nuclear power stations and aircraft. Inspection is carried out during the manufacture of capital and consumer products from children's toys to automobiles to ensure quality and fitness for purpose. There are many techniques available for such inspections.
