Borescopes and fiberscopes provide a means to inspect interior areas of critical and corrosion prone components. A borescope is a thin rod shaped optical device that transmits an image from the components interior to the inspector’s eye. Critical areas are designed with access ports for borescope inspections. Fiberscopes work in the same way as borescopes, but they are flexible so that a wider area may be observed. Video imaging may also be incorporated into these devices so that the images can be viewed on a video monitor.
