资源简介：
The dataset comprises 601 speckle patterns generated by modal interference in a mul- timode optical fiber, capturing temperature-induced variations from 0 °C to 120 °C in 0.2 °C increments. Modal interference occurs when multiple modes with distinct phase velocities and propagation constants overlap, causing constructive and destructive interference across the fiber’s cross-section and producing observable speckle patterns. The experimental setup uses a 650 nm semiconductor laser coupled into the multimode fiber via a tail fiber and flange. A heater precisely controls the fiber’s temperature, altering its refractive index and dimensions. An industrial CCD camera captures the speckle patterns, which are then computationally analyzed to study temperature-induced modal interference effects.
