Opaque lens Optical microscopy and spectroscopy both rely on the controlled transmission of light through a sample. But if a sample is covered by an opaque layer – or indeed if a sample itself is ...

A team of researchers in the Netherlands has developed a new imaging technique that can see through opaque materials – despite the fact that such materials scatter virtually all of the light passing ...

The method relies on interference: the incident light is manipulated in such a way that the scattered light interferes constructively to form a sharp focus after it has passed through the opaque ...

Researchers have found a way to make materials that are normally opaque to sound waves completely transparent. Their system involves placing acoustic relays at strategic locations so that sound ...

EPFL researchers have found a way to make materials that are normally opaque to sound waves completely transparent. Their system involves placing acoustic relays at strategic locations so that ...

New experiments show that it's possible to focus light through opaque materials and detect objects hidden behind them, provided you know enough about the material.

Researchers show how it is possible to look through opaque materials.

New Tunable Windows Turn Opaque With a Switch; Technology is potentially simpler and cheaper to manufacture than previous designs ...

Opaque or translucent materials can produce shadows. Opaque materials, like a brick or a toy, completely block light and create a shadow on the opposite side of where the light is coming from.

Researchers have developed a new X-ray method which involves solving a giant 3D Sudoku problem to better understand these granular movements -- and the findings could have a big impact on various ...

The transmission of light through opaque media is a complex process, owing to the many scattering processes of light. Here, the authors develop a method to determine the transmission eigenchannels ...
