| Popis: | 95 Three-dimensional measurement systems of high precision have been widely applied in high-technology industries and bio-medical areas, especially for micro-scale accuracy measurement. However, due to their bulky volume, most of current surface profilometers cannot perform 3-D measurement within a space-restricted inspection environment. To overcome this drawback, a fiber-based 3-D surface profilometer was developed according to confocal and digital fringe projection principle. Measurement of small objects within a limited space can be achieved by the profilometer which comprises a digital fringe projection system, coherent image fibers and optical lenses. Using confocal measurement and accurate calibration method, the proposed system can obtain out-of-plane depth and reconstruct clouds of surface points accurately. |
