Getting more information by measuring faster and averaging less

For signals barely larger than the noise in a system, measurement is generally a trade-off between speed and precision. Averaging over several measurements reduces the influence of noise but takes (a lot of) time. That could ...

Novel gel proves itself to be a highly tunable color filter

Color these scientists happy. An exotic gel they studied at the National Institute of Standards and Technology (NIST) has an unexpected property: The material's temperature determines which color of light can pass through ...

Tiny lab on a chip analyzes very small volumes of liquid

Scientists from the Institute of Laser Engineering at Osaka University created a prototype terahertz optical spectroscopy system with a sensing area equivalent to the cross-sectional area of just five human hairs. By measuring ...

Light traveling in a distorting medium can appear undistorted

A team led by researchers at the University of the Witwatersrand in Johannesburg, South Africa, with collaborators from the University of Pretoria (South Africa), as well as Mexico and Scotland, have made a new discovery ...

Ultra-thin film creates vivid 3D images with large field of view

Researchers have developed a new ultra-thin film that can create detailed 3D images viewable under normal illumination without any special reading devices. The images appear to float on top of the film and exhibit smooth ...

Broadband perfect absorber scheme for light absorption

Researchers from the Shanghai Institute of Optics and Fine Mechanics (SIOM) of the Chinese Academy of Sciences have recently proposed a design concept for a tunable broadband perfect absorber based on non-split coupling of ...

Physicists shine light on solid way to extend excitons' life

Optics researchers at The University of Texas at Dallas have shown for the first time that a new method for manufacturing ultrathin semiconductors yields material in which excitons survive up to 100 times longer than in materials ...

How holographic interferometry could influence the future

Holographic interferometry is the technique of measuring stress, strain, and vibration with light. It is defined by the wavelength of light, finding flaws in structural bonds. It makes full use of a hologram's ability to ...
