Abstract:A new approach is made as an alternative to existing technologies to obtain Near Infrared (NIR) finger vein images. The new implemented technique is done with the use of a line-scan charged couple device. The scanning process consists of a finger sliding perpendicularly to a line sensor, coated with an infrared-pass filter and an illumination technique of LTM (Light Transmission Method). It was found that this technique is viable to acquire some vascular features of fingers in the NIR spectrum. Contrast, resolution and vertical displacement tests show that the requirements for finger vein image obtainment are met by this procedure. The results exhibit knuckles and veins which shows a direct consistency with respect to the real spatial position in the finger. Therefore proving this technology as a candidate for future finger vein imaging.
