海冰高光谱辐射测量系统的设计及应用

海冰是地球气候系统中的关键要素之一，为此设计了用于测量海冰光学特性的海冰高光谱辐射测量系统，可实现3个通道的同时测量，设计了2种类型的光学探头，解决了探头水密性的问题，搭配“L”型支架实现冰下辐射的现场测量。设计了双向反射率支架，搭配角度传感器可实现探头于任一角度位置对海冰双向反射率的测量。系统积分时间智能设定，实现了积分时间设定的最优化和自动化。解决了低温工作的难题。另外系统还集成了4个温度探头和1个全球定位系统GPS。通过在辽东湾附近海域对海冰的现场实验，验证了系统的可靠性及准确性。

Design and Application of Hyperspectral Radiation System for Sea Ice Observation

Sea ice plays an important role in the global climate system. In the present article, a hyperspectral radiation system for the observation of optical properties of sea ice was designed. The system consists of three optical channels, which can operate simultaneously. Two kinds of optical detectors were designed, and the problem relevant to the water-tightness was resolved. The system can be used to measure the solar radiation beneath the sea ice by an “L” bracket. Another bracket for detecting bidirectional reflectance was designed, which can fix the optical detector at any angle ranging over 0-180 measured with an angle detector. In order to make a most suitable and automatic integrated time, the system can adjust the integrated time intelligently by itself. The system can work stably under extremely low temperature. Furthermore, the system was equipped with four thermistors and one GPS. The system was validated showing a good stability and veracity in situ in the Liaodong Bay.
