A novel system of digital fringe profilometry technique is presented, which used newly improved camera technology preferred by the dermatological industry and a projector, both are commercially available, with new configuration suitable for skin measurement. The system is configured with certain height and angle to respectively project fringes and obtain images. Images will later be processed using phase shifting interferometry (PSI) and global phase unwrapping. The processing system will produce wrapped phase and absolute phase value. In order to prove system's feasibility, experiment was done by sampling two areas from three fingers. Quantitative analysis was done through statistical paired T-Test to see the system ability to acknowledge significant difference of two groups' skin topographic condition. Based on the T-Test, P value that was obtained is 0.003915, which concluded that the system is capable of quantifying two different skin topographic conditions and provide significantly different results. |
