Help Finding a Simple Fiber Optic Sensor for Pressure/Temp Measurement

[s_sekhar]

hello

can someone suggest a simple fiber optic pressure/temperature sensor that can be constructed
...with reasonable accuracy and less equipment...

i came across a few papers about the same...but not sure about the scale and precision required...

please help

thanks

s sekhar, Welcome to Physics Forums!

Accurate and sensitive pressure and temperature sensors can be formed with a simple fiber optic system. Here is some background information to study:

Here is an example of an application:

“Cost-effective assembly of a basic fiber-optic hydrophone for measurement of high-amplitude therapeutic ultrasound fields”:
