Optical illusions aren’t just for fun; they test your focus, observation skills, and mental agility. They play tricks on your brain, making you question what you’re seeing. And if you’re a ...

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 ...

Optical sensors are a broad class of device for detecting light intensity. This can be just a simple component for notifying when ambient light levels rise above or fall below a prescribed level ...

Fibre optics and optical communications is the use of thin strands of glass for sending information encoded into light over long distances. Total internal reflection prevents light inserted into ...

Optical imaging includes a variety of imaging techniques that rely on illumination light in the ultraviolet, visible and infrared regions of the electromagnetic spectrum. The term typically ...

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 ...

Magneto-optics is the use of magnetic fields to influence light propagation. This usually involves changing the physical properties of the medium through which the light is travelling. An example ...

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 ...

All in all, time is of the essence here! After all, what brain teaser is interesting without a time limit? Take another good look at the image and try to spot the Easter eggs in under 7 seconds! Only ...

Apache Calcite is a dynamic data management framework. It contains many of the pieces that comprise a typical database management system but omits the storage primitives. It provides an industry ...

Apr. 23, 2025 — A research team has developed an innovative single-step laser printing technique to accelerate the manufacturing of lithium-sulfur batteries. Integrating the commonly time ...

CD-PFPT effectively transfers knowledge from optical to SAR domains, enhancing ship detection performance in unlabeled SAR images. Our approach consists of two components: pixel- and feature-level ...
