二类水体光学特性研究,特别是高光谱特性研究,是提升中国水色遥感水准的基本条件之一,但商品光谱仪难以应用于混浊水体表观光学特性的测量。本研究通过光纤将水下的光信号引至水面上的光谱仪,使本来专为水面上使用的光谱仪扩展为能够进行水下光学测量的剖面光谱仪,开发出一套适用混浊水体的高光谱剖面测量系统。系统主要包括:1)测量范围从350nm到1050nm的便携式高光谱仪(GER1500,512波段);2)15m的PCS光纤(芯径0.6mm,两端SMA端子),并配合一个自制连接头,使光纤接头能够尽可能地靠近GER1500光谱仪的光栅;3)质量轻、体积小并具有足够强度的浮子装置,为系统水下部分提供海面零基准;...Knowledge of optical properties, especially the hyperspectral properties, of Case-II waters is essential in remote sensing studies of Chinese coastal waters. Application of commercial spectroradiometers is often limited in these turbid waters for a number of reasons. In this study, based on fiber optics and a portable spectroradiometer that has been designed for use in the air, a system has been d...学位:理学硕士院系专业:海洋与环境学院海洋学系_物理海洋学学号:20022700
