摘要	High sensitivity and SNR are requested in lunar astronomical observation in order to get dark and feeble objects. Scientific CCD Cameras used in lunar astronomical observation usually have following characteristics: high quantum efficiency, wide spectral response, good photometric linearity and wide dynamic range. However, extremely low readout noise is usually a key indicator of the camera. A CCD camera, based on E2V's back-illuminated ultraviolet-enhanced scientific grade AIMO image sensor, has been designed for lunar astronomical observation. Four major kinds of electrical optimal design are presented in order to reduce the readout noise of the camera. The experiment result shows that: in the 200K pix/s of the pixel clock, the camera system gain is 1.83e-/ADU, and the readout noise is less than 6e-.
