Fringe projection is an important technology for the measurement of free form elements in several application fields. It can be applied geometry smaller than one millimeter. In combination with deviation analysis algorithms, errors fabrication lines found promptly to minimize rejections. However, some fields cannot covered by classical fringe approach. Due shadowing, filigree on narrow or internal carrier geometries captured. To overcome this limitation, a fiberscopic micro sensor was...
