Optical illusions have a unique way of capturing our attention—they’re fun, tricky, and often leave us second-guessing what we think we see. These clever visual puzzles challenge our minds ...

Harvard scientists created a light beam called an “optical rotatum” that twists and changes torque as it travels, mimicking natural spiral patterns. It offers new possibilities for controlling ...

Traditional optically pumped magnetometers (OPMs) – widely used in submarine detection – face critical “blind zones” in low-latitude regions like the South China Sea, where Earth’s ...

In the video after the break [365 Robots] takes us through the build process of a closed-loop motor with a custom optical encoder. The motor’s body was printed from ABS to withstand the heat ...

Abstract: We propose a magnetic particle imaging (MPI) scanner using an optically pumped magnetometer (OPM) that is connected via a flux transformer. The OPM has high sensitivity, but it cannot ...

Optical materials and structures are substances used to manipulate the flow of light. This can include reflecting, absorbing, focusing or splitting an optical beam. The efficiency of a specific ...
