Controllable Light Scattering on Fiber Bragg Gratings in Multimode Fibers: Tailoring Angular Emission for Advanced Fiber-Based Light

The dataset consists of angular scattering patterns and transmission spectra for two fiber Bragg gratings. The scattering data is represented as 2-D arrays (images). The arrays are rectangular, where the longer side corresponds to the phi angle (azimuth) ranging from 0 to 2pi, and the shorter side represents the theta angle (polar angle) ranging from 0 to pi. To get the angle in rad per pixel just divide the corresponding arc length (p, 2pi) by the number of pixels on the axis.本数据集包含两款光纤布拉格光栅（fiber Bragg gratings）的角散射图案与透射光谱。散射数据以二维数组（图像）形式呈现。该数组为矩形结构，其中较长边对应方位角φ（phi angle），取值范围为0至2π；较短边对应极角θ（theta angle），取值范围为0至π。若需获取每像素对应的弧度值，只需将该轴对应的总弧长除以该轴的像素总数即可。
