摘要
． ST 1000是海洋光学公司生产的多用途光纤光谱仪。它由安装在同一电子电路板上的三台CCD阵列光谱仪组成，由主光谱仪的电子器件驱动。本仪器的光谱波段为350 ~ 850 nm，平均分辨率为0.5 nm。光通过2米长的光纤传导到光栅上。对于数据采集，使用插入板PCMCIA卡。集成时间、扫描次数和它们之间的间隔可以由制造商提供的软件来改变。搭建了现场测量框架，对测量系统进行了标定，并对仪器进行了水生环境遥感适用性测试。并与机载和舰载遥感光谱仪以及水下光谱仪数据进行了比较。我们的研究结果表明，ST 1000光谱仪虽然是为实验室测量设计的，但它可以用于遥感。
FIELD PERFORMANCE OF THE ST 1000 SPECTROMETERIN PASSIVE OPTICAL REMOTE SENSING OF WATER BODIES
. The ST 1000 is a multipurpose fibre optic spectrometer produced by Ocean Optics Inc. It consists of three CCD array spectrometers mounted on the same electronic circuitry board and driven by the electronics ofthe main spectrometer. The spectral band of our instrument is 350-850 nm with average resolution of 0.5 nm. Light is conducted to the gratings through 2 m long fibre optics. For data acquisition a plug-in board PCMCIA card is used. Integration time, number of scans, and the interval between them can be varied by software provided by the manufacturer. We built a frame for the instrument to carry out field measurements, calibrated the measuring system, and tested the suitability of the instrument for remote sensing of aquatic environments. Comparison with airborne and shipboard remote sensing spectrometers as well as underwater spectrometer data was carried out. Our results show that the ST 1000 spectrometer can be used in remote sensing although it is designed for laboratory measurements.
