Physicists solve 2,000-year-old optical problem

A trio of physicists from the National Autonomous University of Mexico and Tec de Monterrey has solved a 2,000-year-old optical problem—the Wasserman-Wolf problem. In their paper published in the journal Applied Optics, ...

Researchers design a light-trapping, color-converting crystal

Five years ago, Stanford postdoctoral scholar Momchil Minkov encountered a puzzle that he was impatient to solve. At the heart of his field of nonlinear optics are devices that change light from one color to another—a process ...

Non-invasive imaging method spots cancer at the molecular level

Researchers for the first time have combined a powerful microscopy technique with automated image analysis algorithms to distinguish between healthy and metastatic cancerous tissue without relying on invasive biopsies or ...

Lessons of conventional imaging let scientists see around corners

Along with flying and invisibility, high on the list of every child's aspirational superpowers is the ability to see through or around walls or other visual obstacles. That capability is now a big step closer to reality as ...

New toolkit for photonics: Quantum simulation by light radio

Intensive research is being carried out on quantum simulators: they promise to precisely calculate the properties of complex quantum systems, when conventional and even supercomputers fail. In a cooperative project, theorists ...

System to image the human eye corrects for chromatic aberrations

Researchers report a new imaging system that cancels the chromatic optical aberrations present in a specific person's eye, allowing for a more accurate assessment of vision and eye health. By taking pictures of the eye's ...
