Tuesday, April 27, 2010. The European Extremely Large Telescope; Adaptive Optics and Resolution Power. Europe has recently announced the construction of the world's largest optical telescope the imaginatively named European Extremely Large Telescope (E-ELT). And it is extremely large - though not as large as the proposed Overwhelmingly Large Telescope, that was scaled down to this project. But why have such a large mirror? What are the advantages? Another important issue is the resolving power of the mir...

Wednesday, July 21, 2010. Cool flexible OLED display. Ok, so it has been a while since the last post. This is very interesting though;. Samsung are on the verge of releasing a new plastic OLED display. The electronics of course will be on a different board, but the entirity of the screen itself is made of plastics thin films and organic materials and is very flexible. It's so flexible in fact that you can smack it with a hammer and it won't break. look at this:. Posted by The Optics Guy.

The Light Side of Science: Quickfire Question: How do LEDs work?
http://thelightsideofscience.blogspot.com/2010/04/quickfire-question-how-do-leds-work.html
Tuesday, April 13, 2010. Quickfire Question: How do LEDs work? LEDs, or Light Emitting Diodes are very common devices used in a wide variety of applications from some street signage, power indicators, transmitters in remote controls and even LED torches. They are very efficient devices, which much like sodium lamps, convert most of the current passing through them into light, with very little loss as heat, but how do they work? Producing a very limited spread of colour in each LED, however the addition o...

Friday, January 15, 2010. The Ancient History of Optics. Not all of these early studies were limited to the Greek and Roman empires though, much important early work was also carried out by Arabic scholars such as Ibn Sahl (10th century BC) who discovered the law of refraction (now known as Snell's law) and Ibn Al-Haytham (10th-11th century BC) who did away with Empedocles' rays from the eyes and more carefully defined what the rays were.

Sunday, February 28, 2010. Quickfire Question: Why are street lamps amber? We are familiar with the colour of many street lamps, the amber glow of the sodium vapour:. But how do these lamps work, why are they the colour that they are, and why do we use them? 1) How do Sodium Lamps Work. They emit light at a very particular wavelength - the amber light that we see. 2) Why are Sodium Lamps that colour? 3) Why do we use sodium lamps? Posted by The Optics Guy.

The Light Side of Science: Quickfire Question: How do Fiber Optics work?
http://thelightsideofscience.blogspot.com/2010/04/quickfire-question-how-do-fiber-optics.html
Tuesday, April 27, 2010. Quickfire Question: How do Fiber Optics work? When you stick something in water - something like a pencil or a ruler is best since they are straight, you can see the object appear to bend at the surface of water. This is due to the differences in refractive index between the water and the air. All materials have a refractive index, because of the way that they interact with light. The vacuum, free space, has a refractive index " n. In a previous post, I mentioned Snell's Law.

Wednesday, March 3, 2010. Light and the Age of the Universe - The Discovery and Analysis of the CMB. Discovery of the Cosmic Microwave Background. The antenna where they made this discovery is now a national monument in the US:. The Cosmic Background Explorer. These results earned another Nobel Prize, but this time for the principal investigators on the COBE project; George Smoot and John Mather. The CMB wasn't the only thing that COBE was analysing however, and there were other important experiments...

The Light Side of Science: Basic Optics: The principles of imaging - lenses and pinholes
http://thelightsideofscience.blogspot.com/2010/04/basic-optics-principles-of-imaging.html
Monday, April 12, 2010. Basic Optics: The principles of imaging - lenses and pinholes. We are all familiar with imaging - everything we see results from the imaging of the world on to our retina. Cameras image the world onto a film or a CCD, usually through a lens. Projectors display images on a screen, but how and why does imaging work. Finally, if we introduce a lens into the larger hole, the light is bent so that (if the object and image are in the right places) all the light passing through the hole ...
