A Group at Going Nova 2007As part of the workshop you can see a heat map of yourself using an infrared camera.

The world appears quite different when you look at it with wavelengths of light beyond the ‘visible’ part of the spectrum which we see with our eyes. To do this requires cameras which collect the non-visible wavelengths turning them into pictures which we can see.

This image is coming directly from the infrared camera and actually shows heat emitted from your body.

The coloured bar on the right shows how the colours in the image correspond to temperature.

Faces viewed at different wavelengthsThis infrared camera records light with wavelengths around one ten-millionth of a metre which is about twenty times longer than visible light. A millimetre wave camera can also show heat but in a slightly different way since the wavelengths are a further 300 times longer than those collected by the infrared camera.

Hair appears cold since it is insulating and doesn’t let heat escape from your head. Your nose and ears are usually the coldest part of your head whereas your eyes are generally the hottest part.

Although visible light (light that our eyes see) can go through glass, infrared light can't and that is why glasses look black.

'Vision For The Future' is an EPSRC funded project run by the MMW group at the University of St Andrews
