摘要

The optical measurement system is for the detection of defects in a surface and comprises a lighting system with a light source and an optical system, which can apply thin shafts of light with well-defined distance between shafts. A camera and key algorithms are used to calculate both the low frequency variation of a surface and that of high frequency. - Triangulation is used to determine the distance that each measured point has from a base surface or from the camera used.
