Multimode fiber optic temperature transmission
As a laser beam passes through a multimode fiber (MMF), a speckle pattern is generated, which is sensitive to temperature, thereby making the MMF a temperature-sensing element. Using experimentally measured multi-temperature transmission matrix, a set of temperature principal. We developed a fiber-optic temperature sensing method using Convolutional Neural Networks (CNNs). The temperature and strain dependences on the core diameter, numerical aperture (NA), and the length of the MMF section in the single-mo e{multimode{ single-mode (SMS) ber structure are investigated experimentally.
