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: \[ \boxed{\text{(4) Conducting sensors}} \]
