A ray of light passes through an irregular medium and displays the same image on the detector that can be recognized without the medium

A team of scientists discovered that it is possible to create “indestructible” rays of light that do not change virtually when passing through a medium. They just get weak.

Scientists from Utrecht University in the Netherlands and Vienna Technical University in Austria have created light waves that are capable of penetrating. Material Opaque.

These beams of light that are “practically indestructible” do not change when passing through a medium, they only attenuate, and remain “static on dispersion.”

to me EurekAlertLight waves can be formed in countless different ways. Stefan Reuter, of the Institute for Theoretical Physics at the Technical University of Vienna, explained that each pattern of light waves “changes and deflects in a very specific way, when sent through an unorganized medium.”

To create light waves that penetrate into opaque materials, it is necessary, first of all, to accurately determine the properties of the materials to be observed.

The team used a layer of Zinc oxide powder Opaque To analyze how light was scattered by this material and what would have happened if dust had not been present.

“As we were able to show, there is a very specific class of light waves, which is Constant patterns of light scattering, Which produces the exact same wave pattern in the detector, regardless of whether the wave of light was being sent through the air or whether it had to penetrate the complex zinc oxide layer, ”Rutter said.

In this experiment, scientists noticed zinc oxide Does not change the shape From these light waves only weakens them.

These discoveries could be extremely useful in biological experiments, namely in introducing light at very specific points to observe Inside cells. The scientific article was recently Published On Nature Photonics.
