Rhodamine concentration with different backgrounds

This dataset in conformed by hyperspectral images captured with the Fx10 camera. The images show the dissolutions of different concentrations of rhodamine. The Rhodamine Water Tracer, hereafter referred to as rhodamine, is a fluorescent dye primarily used as a tracer in aquatic environments. The rhodamine was purchased from ThermoFisher Scientific, identified by the chemical codes CAS 37299-86-8 and 7732-18-5, with catalogue number 446971000. Initially, the rhodamine is highly concentrated at 20%, or 200 g/L, requiring dilution in water to achieve an appropriate concentration for discharge into the sea. This study utilizes 250 mL solutions of seawater and distilled water with varying concentrations of rhodamine. Dissolutions with different concentrations of rhodamine are produced: 1 mg/L, 10 mg/L, 15 mg/L, and 30 mg/L. In addition to the rhodamine dilutions, pure seawater and distilled water samples are also included in the study. These pure samples serve as reference spectra and are essential for the comparative analysis of rhodamine-contaminated samples. The same images are taken with two backgrounds, una light and another dark. The data can be used to test machine learning algorithms such as classification methods.

本数据集由Fx10相机采集的高光谱图像构成。这些图像展示了不同浓度罗丹明的溶液。罗丹明水示踪剂（Rhodamine Water Tracer）后续简称为罗丹明，是一种主要应用于水环境示踪的荧光染料。该罗丹明购自赛默飞世尔科技（ThermoFisher Scientific），其化学登记号为CAS 37299-86-8与CAS 7732-18-5，产品目录号为446971000。初始罗丹明母液浓度高达20%（即200 g/L），需经水稀释至适宜浓度后方可排放入海。本研究制备了250 mL的不同浓度罗丹明海水溶液与蒸馏水溶液，共配制浓度分别为1 mg/L、10 mg/L、15 mg/L及30 mg/L的罗丹明溶液。除罗丹明稀释溶液外，本研究还纳入了纯海水与纯蒸馏水样本。此类纯样本可作为参考光谱，是开展罗丹明污染样本对比分析的必要支撑。所有图像均在两种背景下采集：其一为亮背景，其二为暗背景。该数据集可用于测试分类算法等机器学习算法。
