AI Technical Summary
Existing fiber optic temperature sensors suffer from limited application in practical engineering due to the fixed materials and structure of ordinary optical fibers, resulting in small sensing range, low sensitivity, complex structure, and high cost.
By employing microstructured optical fibers based on the Sagnac ring interference effect, and introducing temperature-sensitive materials and specific hole structures into the optical fibers, high-precision temperature measurement can be achieved by utilizing the birefringence effect of the microstructured optical fibers and the Sagnac ring interference effect.
It significantly improves the sensitivity and measurement accuracy of the sensor, has a simple structure and low cost, and is suitable for biochemical detection and engineering environmental detection.
