摘要
研制了基于干涉滤光片分光的船载多波段水下光谱辐射计 ,该辐射计可同步观测 12波段下行光谱辐照度、12波段上行光谱辐照度和 7波段上行光谱辐亮度 ,水下剖面测量深度达 2 0 0m。在水槽中测定了辐照度探头的余弦响应特性和浸没因子 ,利用MonteCarlo方法模拟了阴影误差分布 ,给出了仪器的主要性能指标。
An underwater spectroradiometer are designed to measure the apparent optical properties of of the upper water column. This new instrument can measure downwelling and upwelling irradiance at twelve wavelengths and upwelling radiance at seven wavelengths simultaneously. The center wavelength and bandwidth of each channel is compatible to that of remote sensors such as SeaWiFS. The new instrument's design criteria, radiometric characteristics and field experimental data are described.
