Visual Testing (VT) Practice Exam

Which remote visual examination aid is designed for viewing around corners?

1. Optiscope

2. Fiberoptic borescope

3. Mirror

4. Image guide

The correct answer is: Fiberoptic borescope

The fiberoptic borescope is specifically designed for inspecting areas that are otherwise difficult to access, including viewing around corners. This tool utilizes flexible fiberoptic cables to transmit light and images, allowing inspectors to navigate through tight spaces and observe surfaces that are not in direct line of sight. The design of the borescope makes it ideal for situations where traditional straight-line viewing tools would be ineffective. This capability is crucial in various fields, such as maintenance, automotive inspections, and engineering, where accessing hidden areas may be necessary for a thorough examination. The other options, while useful in their own right, do not provide the same level of access and visualization capabilities for corner viewing. For instance, mirrors can reflect images around corners, but they typically do not offer the in-depth visibility that a borescope provides. Similarly, the Optiscope and image guides may have specific applications but lack the flexibility and comprehensive viewing ability of a fiberoptic borescope in this context.
