Instrument Response Function Measurement for Macroscopic Painting Imaging

This is the dataset used for calibrating the SPAD camera timing skew and to generate an instrument response function for the FLIM macroscopic imaging system. This dataset is an input to the MATLAB SPADlinearization.m script and is associated with the data in the article "Visualising Varnish Removal for Conservation of Paintings by Fluorescence Lifetime Imaging (FLIM)". <br> The measurement was obtained from the macroscopic FLIM setup used without an emission filters and with a piece of office paper as the scattering sample. The dataset is used to create calibration structures for the two optical systems (macroscopic and microscopic). The calibration structures can be reproduced by running the <em>SPADlinearization.m</em> script. Both the resulting calibration structure and the scripts are available in another dataset in this collection called "SPAD Linearization Code". <br> <br>本数据集用于校准单光子雪崩二极管（Single-Photon Avalanche Diode, SPAD）相机的时序偏移，并为宏观荧光寿命成像（Fluorescence Lifetime Imaging, FLIM）系统生成仪器响应函数。本数据集为MATLAB脚本SPADlinearization.m的输入数据，且与发表于论文《利用荧光寿命成像（FLIM）实现绘画文物保护中的清漆去除可视化》中的实验数据相关联。 本次测量所用的宏观FLIM装置未安装发射滤光片，且以一张办公用纸作为散射样本。 本数据集可用于为宏观与微观两套光学系统构建校准结构。 通过运行SPADlinearization.m脚本，即可复现该校准结构。 生成的校准结构与该脚本均可在本数据集合集内名为"SPAD Linearization Code"的另一数据集中获取。
