You might expect that an opaque material will always hinder the transmission of light by absorbing or scattering any light that is shone on it. But by carefully preparing a beam of laser light, ...

Imaging in disordered materials such as biological tissues or the atmosphere is complicated by the inherently inhomogeneous refractive index, reflecting much of the incident light back and hindering ...

A seemingly paradoxical prediction in physics has now been confirmed in an experiment: No matter whether an object is opaque or transparent, the average length of the light's paths through the object ...

Researchers have found a new way to see through opaque materials with the help of light. This could be done by recording wavelengths from visible light, which can pass through solid material like ...

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. Materials such as paper, paint, and ...

Light propagating in a layer of scattering nanoparticles, shows the principle of diffusion - like tea particles in hot water. The deeper light is penetrating into the layer, the lower the energy ...

Opaque materials can transmit light when excited by a high-intensity laser beam. This process, known as optical bleaching, induces a nonlinear effect that temporarily alters the properties of a ...

Let's Learn is available to stream on pbs.org and the free PBS App, available on iPhone, Apple TV, Android TV, Android smartphones, Amazon Fire TV, Amazon Fire Tablet, Roku, Samsung Smart TV, and ...

Human flesh is opaque. As any good dictionary will tell you, that means it has the quality of “not transmitting light; being impenetrable to sight.” Well, forget that: scientists now can use light to ...
