6.3.2. Fiber Bragg Grating (FBG) Sensors

Try these first

1. 1.

   What does FBG stand for?

   Hint

   Think about the first letter of each word.

2. 2.

   True or False: FBG sensors can detect changes in temperature.

   Hint

   Consider their sensitivity.

3. 3.

   What is the primary principle that Fiber Bragg Grating sensors operate on?

   • Capacitive response
   • Wavelength shift
   • Thermal expansion

   Hint

   Think about how light interacts with materials.

4. 4.

   True or False: FBG sensors are affected by electromagnetic fields.

   • True
   • False

   Hint

   Consider their construction.

5. 5.

   Design a monitoring system using FBG sensors for a new bridge project. Outline key factors to consider, including environmental conditions, locations for sensor placement, and data interpretation.

   Hint

   Consider the aspects that make a bridge structurally sound.

6. 6.

   Assess how the use of FBG sensors can enhance safety in tunnel construction. Provide specific examples.

   Hint

   Think about how to foresee potential issues before they occur.
