摘要 研发了一种向下光谱辐照度和向上光谱辐亮度的锚链式水下多光谱辐射计,主要用于深层海水的测量。解决了水下光学窗口的污染问题。采用高灵敏度光电探测器与高精度ADC相结合的方法探测了深层海水的微弱光信号。电池的使用采用了时钟控制和间断供电方式。通过电感式Modem实现了数据的实时传输。 An underwater multi-channel radiometer, which can be moored on the optical buoy for time series observation of downwelling spectral irradiance and upwelling spectral radiance in seawater, is designed. The biofouling on optical window is protected successfully by using an auto-operated mechanical anti-biofouling-blush. High-sensitivity electrophotonic detector and high precision ADC are combined to detect the weak optical signal in deep water. This instrument is powered by self-stored battery and discontinuous power supply mode is used in order to reduce the power consumption. The real time communication between the radiometer and the control center of ocean optical buoy is achieved by using an underwater inductive modem. The instrument has the characteristics of high accuracy, low power consumption and low self-shading error.
