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.

本数据集包含由Fx10相机拍摄的高光谱图像（hyperspectral images）。这些图像展示了不同浓度罗丹明（rhodamine）溶液。罗丹明水示踪剂（Rhodamine Water Tracer，下文简称罗丹明）是一种荧光染料，主要用作水生环境中的示踪剂。该罗丹明购自赛默飞世尔科技（ThermoFisher Scientific），其化学编码为CAS 37299-86-8与7732-18-5，产品目录号为446971000。该罗丹明初始浓度高达20%（即200 g/L），需在水中稀释至合适浓度后方可排放入海。本研究制备了250 mL的海水与蒸馏水溶液，其中罗丹明浓度各不相同。共配制了以下不同浓度的罗丹明溶液：1 mg/L、10 mg/L、15 mg/L及30 mg/L。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。这些纯样本可作为参考光谱，对罗丹明污染样本的对比分析至关重要。本研究采用两种背景采集图像：una光照环境与黑暗环境。该数据集可用于测试分类方法（classification methods）等机器学习算法（machine learning algorithms）。
