Andrew Beale answered on 28 Dec 2013:
The Veinviewer uses near-infrared light to detect vessels under the skin and projects a real time picture onto the surface. This works because the infrared light is absorbed by blood and reflected by surrounding tissue. This information is captured and processed and the software in the machine calculates where the vessels are. The result is projected in real time directly onto the surface of the skin – the green image you saw on the TV was this result. Quite amazing!

Does it detect arteries and capillaries?
Andrew commented on :
Yes, it should do as the near-infrared wouldn’t differentiate between deoxygenated and oxygenated blood. The only restriction would be the size of the capillaries – very small capillaries will be harder to detect.
