Time-resolved luminescence image sequences for temperature mapping and calibration in a synthetic porous medium

This dataset contains time-resolved luminescence image sequences acquired during a hot water injection experiment in a two-dimensional porous medium. A subset of 10 time points is provided, corresponding to the temperature maps shown in the manuscript. For each time point, the dataset includes a sequence of 2633 raw image frames used to compute the luminescence decay and infer temperature fields. In addition, the dataset includes luminescence image sequences acquired under uniform thermal conditions at selected temperatures, used for calibration of the lifetime-temperature relationship. Each calibration dataset consists of a sequence of raw image frames acquired under steady temperature conditions. A seperate single dataset of image sequences acquired at room temperature are also provided to assess the pixel-wise relationship between excitation intensity and measured lifetime. The full dataset is not included due to size constraints but is available from the corresponding author upon request.本数据集涵盖二维多孔介质热水注入实验中采集的时间分辨发光图像序列。本次公开的子集包含10个时间点的图像数据，对应手稿中展示的温度场分布图。针对每个时间点，数据集均附带2633幅原始图像帧序列，可用于计算发光衰减并反演温度场。此外，数据集还包含在选定温度的均匀热工况下采集的发光图像序列，用于校准寿命-温度之间的关联关系。每组校准数据集均由稳态温度条件下采集的原始图像帧序列组成。另有一组独立的室温图像序列数据集，用于评估激发强度与实测寿命之间的逐像素对应关系。受文件体积限制，完整数据集未随本数据集一同发布，如有需求可向通讯作者索取。
