Ultra-compact optical design enhances virtual and augmented reality device cameras

Posted by in categories: augmented reality, drones, mobile phones, nanotechnology, virtual reality

Researchers from Seoul National University College of Engineering announced they have developed an optical design technology that dramatically reduces the volume of cameras with a folded lens system utilizing “metasurfaces,” a next-generation nano-optical device.

By arranging metasurfaces on the so that light can be reflected and moved around in the glass substrate in a folded manner, the researchers have realized a with a thickness of 0.7mm, which is much thinner than existing refractive lens systems. The research was published on Oct. 30 in the journal Science Advances.

Traditional cameras are designed to stack multiple glass lenses to refract light when capturing images. While this structure provided excellent high-quality images, the thickness of each lens and the wide spacing between lenses increased the overall bulk of the camera, making it difficult to apply to devices that require ultra-compact cameras, such as virtual and augmented reality (VR-AR) devices, smartphones, endoscopes, drones, and more.

Experiment suggests quantum computers can coordinate actions of moving devices

Posted by in categories: drones, quantum physics, robotics/AI, space travel

New research from the University of Kent has demonstrated that quantum information could eventually be used to coordinate the actions of devices that can move, such as drones or autonomous vehicles. This could lead to more efficient logistics, which could make deliveries cheaper, and better use of limited bandwidth for the likes of self-driving cars.

By carrying out “real world” experiments on a quantum computer, the team of quantum physicists (led by Ph.D. student Josh Tucker in the University of Kent’s School of Physics and Astronomy), found that if the two devices share a pair of quantum coins (), the devices can continue to influence each other even after they have been separated and can no longer communicate.

The experiments simulated the phenomenon using real qubits inside a quantum computer developed by IBM. The qubits are made of superconducting material and kept at temperatures colder than the interstellar void. This allows them to behave according to the laws of quantum physics that defy common sense—including the ability to influence each other without coming into contact and without sending signals.

As Elon Musk pushes driverless cars, one company is already testing autonomous helicopters to spray crops and fight fires

Posted by in categories: drones, Elon Musk, food, robotics/AI

The heart-stopping flights led to his research of unmanned aircraft systems while getting his doctorate degree in aerospace engineering at Massachusetts Institute of Technology. Then, he formed Rotor Technologies in 2021 to develop unmanned helicopters.

Rotor has built two autonomous Sprayhawks and aims to have as many as 20 ready for market next year. The company also is developing helicopters that would carry cargo in disaster zones and to offshore oil rigs. The helicopter could also be used https://apnews.com/article/wildfire-season-2024-firefighters…2e4c66fd7” rel=“noopener”>to fight wildfires.

For now, Rotor is focused on the agriculture sector, which has embraced automation with drones but sees unmanned helicopters as a better way to spray larger areas with pesticides and fertilizers.

China’s new microwave weapon can fry enemy drones 2 miles away

Posted by in categories: drones, energy, military

China’s latest weapon, unveiled during an air show in Zhuhai, could be a game-changer during possible future conflicts with rival powers.


China is making advancements in its multiple military-related technologies that will give it an edge over its adversaries during a possible conflict in the future. During a recent giant air show in Zhuhai, Beijing unveiled multiple game-changer military technologies, including a mobile air defense weapons system.

Called FK-4000, the mobile air defense weapons system is reportedly capable of intercepting the smallest, lightest drones using its high-power microwaves (HPM).

Researchers Discover Enormous Ancient Cities Hidden in Uzbekistan’s Mountains

Posted by in category: drones

Using drone-based lidar, researchers mapped two medieval cities, Tashbulak and Tugunbulak, in Uzbekistan, revealing detailed urban structures significant to the Silk Road’s history.

The first use of drone-based lidar in Central Asia has enabled archaeologists to uncover details of two newly discovered medieval trade cities high in the mountains of Uzbekistan.

The team used this cutting-edge technology to map the archaeological scale and layout of the cities, which are among the largest ever documented in the mountainous parts of the Silk Road, a broad network of ancient trade routes that connected Europe and Eastern Asia.

Launch Report: SpaceX Launches Starlink 6–68

Posted by in categories: drones, internet, satellites

SpaceX sent another group of Starlink satellites to orbit aboard a Falcon 9 launched from Space Launch Complex 40 this morning. Liftoff was at 8:21 AM.

Around 8.5 minutes later, Falcon 9 booster B1076 touched down offshore on ASDS ‘Just Read The Instructions’, which had been pre-positioned off the coast of The Bahamas in the Atlantic Ocean. The drone ship will return to Port Canaveral and B1076 will be returned to SpaceX’s Hangar X for inspection and, presumably, preparation for its next flight.

Researchers Develop System Cat’s Eye-Inspired Vision for Autonomous Robotics

Posted by in categories: drones, robotics/AI

Feline-inspired vision technology enhances accuracy in challenging environments, paving the way for smarter, more efficient autonomous systems.

Researchers have unveiled a vision system inspired by feline eyes to enhance object detection in various lighting conditions. Featuring a unique shape and reflective surface, the system reduces glare in bright environments and boosts sensitivity in low-light scenarios. By filtering unnecessary details, this technology significantly improves the performance of single-lens cameras, representing a notable advancement in robotic vision capabilities.

Autonomous systems like drones, self-driving cars, and robots are becoming more common in our daily lives. However, they often struggle to “see” well in different environments — like bright sunlight, low light, or when objects blend into complex backgrounds. Interestingly, nature may already have the solution to this problem.

Laser, microwave, and other directed-energy weapons ready for the battlefield

Posted by in categories: drones, energy, military, surveillance

Perhaps no technology has shaped the 21st-century battlefield as profoundly as the drone. These uncrewed aerial vehicles (UAVs), along with their land and sea counterparts, have redefined the way wars are fought by providing military forces with unprecedented capabilities in surveillance, precision targeting, and intelligence gathering — all while reducing the risk to their own personnel. Drones have made complex operations more efficient and less costly, enabling militaries to strike with pinpoint accuracy and maintain a persistent presence over the battlefield.

As the century progresses, the influence of drones continues to expand beyond traditional state actors. Non-state groups and non-peer adversaries increasingly have adopted this technology, leveraging it to level the playing field in conflicts around the world. With commercial drones becoming more accessible, these actors can conduct reconnaissance, drop bombs, and challenge conventional military forces in ways that previously were unimaginable.

The influence of drones flows across all domains of warfare. Loitering munitions, or “Kamikaze drones,” have disrupted traditional force structures by providing smaller, more agile units with the ability to strike high-value targets such as tanks, artillery, and command centers.
