Researchers have invented a new quantum holography technique that images objects using undetected light. This counterintuitive process, which involves two correlated beams of nonclassical light in an ...

Optical imaging devices have become ubiquitous in our society, and a trend toward their miniaturization has been inexorable. In addition to facilitating portability, miniaturization can enable imaging ...

If you think X-rays and other forms of radiation have a monopoly on penetrating opaque objects, visible light begs to differ. It actually can pass through things like paint and human tissue, which has ...

Researchers have uncovered new rules governing how objects absorb and emit light, fine-tuning scientists' control over light and boosting research into next-generation solar and optical devices.

Researchers demonstrated a new type of optical manipulation: using laser light to pull a macroscopic object. The technology has potential for applications in the continued explorations of Mars.

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. Back in 2018, astronomers examining the ruins of two collided ...

A team of scientists says they've found a specific kind of light wave that can pierce directly through objects, making it seem as though they were totally invisible. This new approach, however, is a ...

Researchers at Caltech have designed a way to levitate and propel objects using only light, by creating specific nanoscale patterning on the objects' surfaces. Though still theoretical, the work is a ...

For several centuries now, scientists have known that light behaves like a wave, expanding out from its source until absorbed or reflected by objects, which are in turn illuminated. In recent years, ...

Once thought of as the province of only "Star Trek" or "Harry Potter," cloaking technologies could become a reality with a specially designed material that can mask itself from other forms of light ...
