Photometers or light meters are radiometers that include a filter and photodiode and responds based on the average human eye: the CIE 1924 luminosity function V λ. However, the light sensitive diode ...
If there’s an engineering hierarchy of LED lighting, colour-mixing hard lights are at the top of it, combining all the difficulty of colour control with putting all the emitters in one place. For a ...
How matter responds to light lies at the core of vision, photosynthesis, solar cells, and many other fields of scientific and practical import. But until now, it hasn't been possible to see just how ...
A multicolor laser pointer you can use to change the color of the laser with a button click -- similar to a multicolor ballpoint pen -- is one step closer to reality thanks to a new tiny synthetic ...
Digital signal processing, holography, and quantum and classical information processing rely heavily upon recording the amplitude and phase of coherent optical signals. One method for achieving ...
We now take LED lighting for granted, but acheiving a specific colour is actually quite complicated. Why is that? At some point, reasonably soon, full-colour mixing will become more the rule than the ...
White light emission from a single two-component molecule is achieved through a frustration of energy transfer between the molecule’s segments. Organic white light emitters are used for display and ...
ALBUQUERQUE, N.M. -- A multicolor laser pointer you can use to change the color of the laser with a button click -- similar to a multicolor ballpoint pen -- is one step closer to reality thanks to a ...
