As a kind of lowlightlevel detector, intensifier charge coupled device (ICCD) is very significant to the research and development of the ultraviolet detection. The ultraviolet detection technology is widely used in the missile warning system, which provides an accurate reference and standard for precise measurement technique of modern equipment. Through adjusting the three dimensional (3D) adjusting machine and the precision guide, the distance was changed between sensitivity surface of light cone CCD parts and microchannel board of flurescence panel of image intensifier, and the image was observed in realtime that gathered from CCD. When the image was the best, the relative distance was surveyed precisely, in order to provide reference data for the following installing and debugging. It provided guarantee that the CCD and the image intensifier had a reliable coupling by the force measured device. The detail design principle of the mechanical part of the system was explained.
