Abstract:Security within passwords and electronic devices has become more important. Therefore, there is an increasing demand for compact finger vein scanners. This research continues with Alvarez’s research on designing a compact finger vein swipe sensor. Since their research managed to visualize the joints within the finger, but failed to distinguish finger veins, the objective of this research is to discover whether it is possible to visualize finger veins with a similar setup. Several experiments were conducted to test and improve the image quality, the dynamic range of the images, the camera and the code. Also a new aperture filter was designed to improve the quality of the images. From the experiments could be concluded that with several improvements it is possible to increase the quality of the images sufficiently to identify finger veins. However, the dynamic range of the images is too low. Theoretically this could be improved by increasing the gain or exposure time of the camera, but the current code does not allow these values to be altered. To conclude, the current setup is not able to visualize any finger veins, since the dynamic range of the camera cannot be sufficiently increased, when supported by the current code.
