Abstract: Incorporate testing was applied for nondestructive testing of the crack in an aeroengine labyrinth. In order to achieve miniaturization and portability of the system, endoscope CMOS image collection system based on embedded microprocessor ARM9 S3C2440 was designed . The CMOS image sensor driver was designed in this paper, and some experiments were carried out in the standard labyrinth specimen using the image collection system. The experimental results show that the system has the merits of high definition and fidelity. So it could meet the image collection needs in incorporate testing.
