Approach of linearity measurement is discussed  and a kind of measurement system of the UV ICCD has been developed based on the method of neutral density filter. It is very important that the transmittance of the filter is independent of the wavelength in the method of neutral density filter. Black metal screen mesh with different transmittance is used in our system  and calibration of the filters' transmittance in different working positions has been done. Meanwhile  to assure the uniform of the received radiation on the target of the detector at any test points  an integrating sphere is placed behind the neutral filter to balance light. The whole measurement system mainly consists of a deuterium lamp with high stabilization  the attenuation film with transmission  integrating sphere  optical guide and electro-shift platform. Auto control is realized via special software during the test. With this instrument  the linearity of the UV ICCD was measured. Experimental results show that the nonlinearity of the UV ICCD under fixed-gain is less than 2% and the uncertainty of measurement system is less than 4%. 2010 Copyright SPIE - The International Society for Optical Engineering.   Variability of UVR effects on photosynthesis of summer phytoplankton assemblages from a tropical coastal area of the South China Sea 会议论文 33rd Annual Meeting of the American-Society-of-Photobiology, San Juan, PR, JUL, 2006 Gao, Kunshan; Li, Gang; Helbling, E.
