What is a fiber optic sensor PM
Fiber optic sensors: PM fibers are used in sensors that rely on changes in the polarization state of light to measure physical quantities such as temperature, strain, and pressure. These small but powerful devices are designed to control the path of light while keeping its polarization. Radiation absorption creates electronic excited states that are trapped by localized defects for extended periods of time. When light travels through a standard optical fiber, environmental factors like temperature changes, bending, and twisting can cause the.
