Polymeric light emitting diodes (LEDs) have already achieved performance figures comparable to inorganic LEDs.

We can use LEDs.

These blocks represent LEDs.

Most importantly for this, they're faster.

(a) Boosting the production of equipment for the fuel and energy sector, including laser measuring systems, optoelectronic flame control systems, instruments to measure gas density, multiphase pumping plants and control systems for high performance gas pumping stations

And this speed, combined with today's high performance micro controllers, allows us to actually simulate, in this piece, over 17,000 LEDs using just 64.

Furthermore, the high level of research and development in the field of GaAlAs technology promised rapid advances in the development of GaAlAs diode laser communications systems.

LEDs are smaller, they're cheaper, they're longer lasting, they're more efficient.

And when it starts flashing, it's just going to be one of the LEDs that's flashing very fast.

It achieves this by rotating LEDs about two axes.

It's just 16 blue LEDs that we can program to do different types of displays.

These LED's are wired to sensors that detect the presence of odorous molecules in the air.

I've got a little video to show you, but keep in mind that this is with no electronic control, and this is also with only four LEDs.

Now we have LED, but here you see the latest one, and you see how incredibly small it is.

At the Andøya Rocket Range, scientific rockets are launched and the international Arctic Lidar Observatory for Middle Atmosphere Research (ALOMAR) facility uses light detection and ranging (lidars) to study the middle and upper atmosphere.

And so we can control that with micro controllers and create a fully volumetric, three dimensional display with just 256 LEDs.

The enemy used lasers.

In this electronic toy circuit, the mushroom body neurons are symbolized by the vertical bank of blue LEDs in the center of the board.

I have solidified the beam of the laser pointer.

Using a unique technique for concentrating the solar light, splitting the spectrum to various spectral bands, and using each band for direct optical pumping of different lasers near their emission band resulted in an overall efficiency of 20 per cent.

The Institute is a member of the International Laser Ranging Service (ILRS) and the European Laser Ranging Service.

Optimum Power Calibration failed.

This is a face scanning sphere, with 156 white LEDs all around that allow us to photograph her in a series of very controlled illumination conditions.

And then the laser actually cuts.

Well, anyway... next morning the sun was shining the ocean was as smooth as glass.

Laser or particle beams as options for active missile defences or otherwise applied in a nuclear weapons context

So this robot is actually equipped with a camera and a laser rangefinder, laser scanner.

And we also projected the contents of the time capsule as binary code using a 35 watt laser into outer space.

So for example, Jackson came along and suggested that we use air pumps instead of water pumps.
