# Revolutionizing Temperature Measurement with Fiber Optic Sensors
## Introduction
Temperature measurement is a critical aspect of various industries, from manufacturing to healthcare. Traditional methods, such as thermocouples and resistance temperature detectors (RTDs), have served us well, but they come with limitations. Enter fiber optic temperature sensors, a groundbreaking technology that is transforming the way we measure temperature.
## What Are Fiber Optic Temperature Sensors?
Fiber optic temperature sensors utilize optical fibers to measure temperature changes. These sensors work by detecting variations in the light properties, such as intensity, phase, or wavelength, as they travel through the fiber. The core principle relies on the interaction between light and the material properties of the fiber, which are temperature-dependent.
## Advantages Over Traditional Methods
