demo is designed to increase awareness that different types
of light can see through different materials. Millimetre waves
can see through lots of materials that visible and infrared
The workshop consists of 3 sets of wave emitters and receivers
at a visible wavelength, millimetre wavelength and infrared
wavelength. The image on the right shows the millimetre wave
transmitter and receiver.
The participants will have the chance to try putting different
materials, like plastic, wood, materials and paper, between
the emitter and receiver and find out whether that wave can
see through the material.
There is a much larger version of this called the 'transmission
wheel' which is shown at bigger venues and when the exhibition
is on tour.
