This paper proposes a miniature gauging system for objects inside a body cavity using the projected fringe profilometry (PSPFP) combined with the endoscope. The fringe pattern is formed by launching a reading bean into a diffraction element . The diffraction element can avoid the influence of projected aberrations by lens and largely reduce the size of projected system. This system has the following properrties: 1. It is a noon-contact, and full field measurement. Only one-shot measurement is needed. It is able to carry on the immediate gauging to the dynamic object. 2. Arrangement of the projected fringe is unique due to the procedure of specific coding. It is easy to revise the errors when undergo phase unwrapping. 3. The double projection scheme compensates the defects of one-shot measurements.

Phase-extraction from fringe patterns is an inevitable procedure in many applications, such as interferometry,Moiré analysis, and profilometry using structured light illumination. However, speckle noises could be introduced when a coherent light source is used. In this thesis, we use the empirical mode decomposition (EMD) to perform the speckle-reduction. It is found that phases can be extracted with high accuracy once speckle-reduction is performed with the EMD.
