Visual Testing (VT) Practice Exam

What term is used to describe visual examination tools that utilize flexible glass strands?

1. Telescopes.

2. Fiberoptic borescopes.

3. Borescopes.

4. Binoculars.

The correct answer is: Fiberoptic borescopes.

The term used to describe visual examination tools that utilize flexible glass strands is fiberoptic borescopes. These instruments leverage bundles of optical fibers to provide illumination and a clear image of areas that are otherwise difficult to access. The flexibility of the glass strands allows for maneuverability in confined spaces, making fiberoptic borescopes particularly useful in industrial inspection, medical procedures, and various engineering applications. The ability to transmit light and images through these flexible strands allows these tools to provide detailed visual feedback without the need for direct line of sight, which is what sets them apart from other optical instruments. Additionally, they often come equipped with high-definition cameras and light sources, enhancing their capability to inspect and document findings in challenging environments.
