Abstract:Biometrics centers around identification based on unique anatomical properties. Such unique properties, are finger vein patterns. These patterns can be recovered from vascular images. Vascular images are captured by near-infrared (NIR) light, which interacts with the finger causing vein projections on the skin. A common problem with these images, is that details in vein patterns reduce in the presence of overexposure. White areas, mostly found on the finger edge, are covering parts of the vein pattern. This effect occurs more often with side illumination. To mitigate this effect, suitable illumination must be applied. This research delves into the question if a side illumination setup can be designed with minimal presence of overexposure. By designing and individually evaluating multiple illuminators, the best suited illumination technique is to be chosen
