Or, if you want the professor's technical explanation, "dye sensitised solar cells with titanium oxide layers on a surface with light absorbing dye molecules adsorbed on surface which can generate electricity".
Visually these boards have a washboard effect-and as the varied grain intersects the wood surface and light at different angles, a hologram-type depth emerges.
Indeed, being focused on odors -- which themselves require air to move, or a surface to light on -- means that for my dogs, the street outside our apartment building is different each time we step out the door.
What if all you needed to tap, swipe and type on was a flat surface and projected light?

The vegetated surface is much darker and absorbs light, which warms the surface.
The output is then relayed into a 1.4 mm thick plastic waveguide lens with input and output hologram structures on the surface which squeezes the light down the waveguide and then two dimensionally expands the image back into the user's eye, creating an image that is then mixed into the real world.

Thus your body and objects that are underneath your clothes will have a somewhat higher temperature than the surface of your clothes and will emit light of a different IR wavelength than the surface of your clothes does.

One thing that I can do right now while traveling is get a sense of what these issues are, bubbling underneath the surface, to bring some light and awareness.
This handheld device measures the different wavelengths or types of light reflected from a surface.
V4, where the light reflected from a surface is compared with that reflected from surrounding surfaces, in order to control for relative rather than absolute brightness.
When light hits a plasmonic surface, it creates a wave of electrons that move at the same frequencies as photons, rather than the much slower frequencies of an electric current.
Though that also makes it more flexible (and makes the ability to grind and polish the glass to create a light-capturing parabolic surface without actually breaking the thing all the more impressive), this flexibility can be exploited to keep the reflective surface in shape.
This light is proportional to the surface temperature, so by measuring its brightness a microprocessor can compute the temperature.
However, once the grade depths were confirmed, light was focused on the surface.
Obviously at 400 feet it's really quite dark but at the surface it starts off being very very light, even without a mask I can tell that.
To remedy this problem, Kylie Catchpole of the Australian National University in Canberra and Albert Polman of the Institute for Atomic and Molecular Physics in Amsterdam have been trying to redirect the light that falls onto the surface of a cell in such a way that all colours are efficiently absorbed.
Ultraviolet light could kill anthrax on the surface of items, but not inside envelopes or packages.
Most photomasks are created by etching away a thin film of light-blocking chrome from the surface of a quartz plate.
Gallium nitride, or GaN, converts electrical impulses to light and is grown on the surface of wafers made from sapphire or silicon carbide.

The other is a non-contact method by detecting intensity of the invisible infrared light that naturally emanates from every surface in this Universe.
Crops need a sheltered environment, protected from the extreme temperatures and frightening levels of radiation found on the moon's surface, with water, carbon dioxide and light.
On the Gateway, the blob was transformed into a richly hued translucent jewel that bounced to the bass while shafts of light played over a rotating 3D surface.
It's that light that's illuminating the surface of the Moon.
It also suggests the amount of aerosols that humans emit into the atmosphere could impact tree growth, as high levels of aerosols cause "global dimming", an effect that occurs when the levels of light reaching the Earth's surface fall.
MOLA, which works by bouncing beams of light off the planet's surface, has found mountains twice as high as Everest, a crater ten kilometres deep, and huge valleys carved by more water than scientists believed had ever existed on Mars.
While the ozone layer in the upper atmosphere plays an important role in limiting harmful ultraviolet light reaching the Earth's surface, low-level ozone is a pollutant that is harmful, causing respiratory problems in animals as well as well-documented cases in humans.
But over time, the white paint would be reflecting light and other electromagnetic radiation from its surface.
FORBES: An Earth-Killing Asteroid Could Be Deflected With Paintballs
But McNamara's men made light of the freezing temperatures and hard surface to deliver an emphatic display.
The first images from space of the distribution of light sources on the planet's surface were published in 1989.
The Corot spacecraft detects the oscillations as subtle variations in the light emitted by the star as the surface wobbles.
