Pushing the limits of structured light, applied physicists report a new type of optical vortex beam that not only twists as it travels but also changes in different parts at different rates to create ...

The infiuence of light ... line of light. The fundamental idea on which rests the possibility of producing speech by the action of light is the conception of what-Mr. Bell terms an undulatory beam ...

The paper, titled "Threading light through dynamic complex media," is published in the journal Nature Photonics. Shine a laser beam onto a moving object and the way the light is scattered will ...

Free-space optical communication, or FSO, is an interesting and easy way to transmit signals through light beams ... For more precision, swap to narrow-beam LEDs or use filtered photo diodes ...

At the end of the line, the beam was turned off and moved back to the left and down one line, known as the "horizontal retrace." When the bottom-right corner was reached, the electron gun was ...
