Question:
Fibre optic sensors may be classified into three categories. Choose the incorrect option.
Fibre optic sensors may be classified into three categories. Choose the incorrect option.
Show Hint
Fibre optic sensors are typically classified into categories such as intensity-modulated, phase sensors, and diffraction sensors.
Updated On: Sep 19, 2025
- Intensity-modulated sensors
- Phase sensors
- Diffraction sensors
- Conducting sensors
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Fibre optic sensors are generally classified into intensity-modulated, phase-sensitive, and diffraction-based sensors. "Conducting sensors" is not a classification commonly used for fibre optic sensors, making it the incorrect option.
Final Answer: \[ \boxed{\text{(4) Conducting sensors}} \]
