Columbia Engineers Revolutionize Augmented Reality (AR) Glasses through novel engineered optical materials (EnMats)

Imagine driving along the highway with directions and other pertinent information (think gas stations) appearing “on” your glasses so you ,don’t have to look away from the road. Or building a complicated DIY project with step-by-step instructions appearing “on” your glasses. Or being a first-responder unsure which way to go, …

Researchers developing efficient Vision Aided Navigation for UAV in GPS-Denied environments like building, underground or under the forest canopy

UAV navigation can be seen as a process that robots make a plan on how to safely and quickly reach the target location, which mostly relies on current environment and location. In order to successfully complete the scheduled mission, a UAV must be fully aware of its states, including location, …

DARPA A-PhI to use photonic integrated circuits (PICs) for developing compact atomic clocks and gyroscopes in GPS denied environments

U.S. military researchers are asking industry to develop relatively simple portable photonic integrated circuits (PICs) for high-performance position, navigation, and timing (PNT) devices as an alternative to the Global Positioning System (GPS) for when GPS signals are not available.   Position, Navigation, and Timing (PNT) is a critical resource for …

Military employing LIDAR in Driverless vehicles, Battlefield Visualization, Mine Hunting, Imaging through forests

Lidars (Light Detection and Ranging) are similar to radars in that they operate by sending light pulses to the targets and calculate distances by measuring the received time.  The  key advantages of  LIDAR is  its superior accuracy and its ability to see through masking items, such as leaves, trees, and …

Airborne or Spaceborne Synthetic aperture ladar (SAL) for centimeter-class resolution battlefield awareness

Conventional optical imagers are limited in spatial resolution by the diffraction limit of the telescope aperture, as well as by the practical difficulties in increasing the telescope aperture. Synthetic aperture (SA) techniques can increase resolution beyond the diffraction limit of the receiving aperture.   Just as synthetic aperture radar(SAR) working …

‘Parallel Reality’: New screen technology that uses ‘magic pixel’ to display personalised content to multiple people

Synaps Labs displayed a billboard in Moscow changed the ad on its display based on the brand of car passing by. The billboard was created by, which used high-speed cameras placed 180 meters in front of the billboard to take pictures of cars. Machine-learning software determined each car’s make and …
