| Abstract: | Conventional vein recognition systems use cameras to obtain near-infrared finger vein images, but the size of these systems can be reduced if the image capture method is changed from a camera to a contact sensor. This study investigates the feasibility of a finger vein recognition system that uses a contact sensor, where the focus will be on what type of sensor is needed to achieve this and how large this sensor should be. To have a sensor with a large enough surface area to capture vein patterns a commercial camera will be converted into a contact sensor. To use this sensor multiple modifications are made to the original camera’s PCB. Furthermore, several collimator designs are tested to see how this affects the projected light on the sensor and the visibility of objects placed in front of the sensor. The resulting images show visible veins when using phantom fingers that have known vein patterns. This shows that finger vein pattern recognition should be feasible if the necessary adjustments are made to the collimators. |
