Tracking how molecules move, form shapes, and interact within neurons and other cells offers a powerful view of biological processes that impact health.
Dispelix Oy, a spinoff of research organization VTT Technical Research, has developed a see-through, near-to-the-eye smartglass display that uses novel waveguide-based optics ...
Applications requiring extremely well-defined illumination patterns may benefit from LEDs modified to control the shape and size of the light aperture.
Ranjith Nair and Mankei Tsang of the National University of Singapore have proposed a framework for estimating the separation of two incoherent point sources of arbitrary closeness...
Making the most of LED light sources requires refinements in color measurement and standards, and an understanding of how the color sensitivity of the eye varies in the range ...
Accurate, repeatable wavelength and intensity information is possible for a spectrometer using an LED source and nonlinear optimization by taking into account variations in system...
Typical fluorescence-based endoscopic imaging cameras consume large amounts of power and are limited to laboratory-scale applications because of their bulky size.
Conversion of abundant, common carbon into bulk diamond is typically accomplished through volcanic action or laboratory environments at very high temperatures and pressures, while...
Because of its high refractive index of about 1.77, the sapphire-based aplanatic numerical-aperture-increasing lens (aNAIL) can produce a higher resolution than ordinary optics...
Splitting water (H2O) through an oxidation process into hydrogen fuel and oxygen or converting carbon dioxide (CO2) into a fuel such as methanol requires a large amount of energy...
The thin-film nature of white organic light-emitting diode (OLED) lighting elements allows them to be made into large-area, glare-free lamps and luminaires shaped unlike any other...
The need for high-power green laser sources for welding copper has driven the development of frequency-doubled disk and fiber lasers emitting in the 515-532 nm spectral region...
Single-element beam expanders containing an aspheric surface can be used in cascade to create different magnifications; an added lens adjusts for wavelength-change effects.
