- Better Thermal Infrared Detection Means Better Seeing In The Dark
Thermal infrared (IR) energy is emitted from all things which have a temperature greater than absolute zero- so, basically all things worth looking at. Though mechanical detection of IR radiation has been possible since Samuel Pierpont Langley invented th ...

- 100 Percent Chance A Milky Way Supernova Will Be Visible From Earth
Astronomers have calculated the odds that, sometime during the next 50 years, a supernova occurring in our home galaxy will be visible from Earth and found the chances to be nearly 100%- and it will be visible from telescopes in the form of infrared radia ...

- Raman Scattering: Taking Fingerprints Of The Infinitely Small
Raman scattering mode is an optical phenomenon, discovered in 1928 by the physicist Chandrasekhara Venkata Raman, that involves the inelastic scattering of photons- the physical phenomenon by which a medium can modify the frequency of the light impinging ...

- The Puzzle Of How Quantum Effects Help Plant Cells Capture Light
Experiments with ultrashort laser pulses support the idea that quantum interactions between molecules help plants, algae, and some bacteria efficiently gather light to fuel their growth- but that's about it. Key details of nature's vital light-h ...

- Speed Up Underwater Communications By 76X- Without Bothering Whales
A project to develop fast-blinking LED systems for underwater optical communications has led to discovering that an artificial metamaterial can increase the light intensity and "blink speed" of a fluorescent light-emitting dye molecule. The nano ...

- Blue Light Has An Immediate Effect On Fatigue
Exposure to short wavelength, blue, light during the biological day directly and immediately improves alertness and performance. In order to determine which wavelengths of light were most effective in warding off fatigue, the researchers teamed with Georg ...

- New Technique Takes Cues From Astronomy And Ophthalmology To Sharpen Microscope Images
The complexity of biology can befuddle even the most sophisticated light microscopes because biological samples bend light in unpredictable ways, returning difficult-to-interpret information to the microscope and distorting the resulting image. New imagin ...

- Metasurface Lens: Flat Surface Becomes A Spherical Antenna
An array of tiny, metallic, U-shaped structures deposited onto a dielectric material creates a new artificial surface that can bend and focus electromagnetic waves the same way an antenna does. ...

- Downside To LED Bulbs- Like HDTV, It Makes Some Things Look Worse
If you have ever seen set pieces from a science-fiction show, you have probably been amazed at how cheap and silly the whole things looks. That was the initial concern with high-definition television too. Standard definition hid a lot of cosmetic defects ...

- Deformable Mirror Corrects Its Own Laser Beam Errors
The high power needed to cut or weld using a laser beam creates its own problem: the beam’s energy deforms the mirrors that focus it. When that happens, the beam expands and loses intensity. A new type of mirror is being presented at the Optatec trade fair ...
