A color 3D object reconstruction system using varifocal lens with various focus algorithms was established in this study. The focal length of the varifocal lens can be regulated by varying the focal power. In this study, four categories of algorithms are applied into the system. The focal length of the system is adjusted by computer control, and the best focal length would be found by the algorithm. When the image of sample is in focus, the image will be the clearest. By finding the best focal length corresponding to each pixel position, we can convert to the height information for reconstructing the threedimensional surface profile.
