摘要

An instrument for fine-machined pipe (long than 10m) inspection and measurement instrument is introduced in this paper. The non-contact interior wall roughness measurement system based on light reflecting and scattering theory has a wide range (Ra from 0.012μm to 4μm) and is suitable for different types of machined surface measurements. The interior diameter is measured by a pair of gratings which produce Moire fringes. The accuracy of which is better than 5μm for a pipe diameter greater than 100mm. A CCD video camera inspection system is also installed on the measuring head to check the interior wall quality.
