In order to overcome the distortion problem of CCD driving signals caused by signal transmission  the detail implementation of transmission of high-speed CCD driving signals based on transmission line theory is discussed. The CCD driving signals are critical to the CCD to produce high quality images. In high speed application these drivers will occupy more circuit board areas and can not be put very close to the CCD. So the driving signals must be transmitted. Because the CCD exhibits capacitive load  the driving signals distortion problem is much severe. Transmission line theory is used to analyze the problem. The method of source termination is adopted to avoid signal reflections. Meanwhile the characteristic impedance of the circuit board and the resistance of terminal resistor are designed small enough to decrease the rising and falling time of the driving signals. Experimental results show that there is no distortion of the high speed driving signals after transmission. 2011 IEEE.

To the characteristic of the ultraviolet CCD (UV ICCD)  technique of the linearity measurement of the UV ICCD camera is studied based on the theory of radiometry. 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.
