LIDAR

Researchers have created a device that uses photonic radar to remotely and accurately monitor breathing, even distinguishing between more than one patient. The device might one day be used in hospitals, aged care facilities, prisons, and at home.

Taking 3D images underwater is tricky due to inconsistent lighting conditions and particles in the water that cause distortion. Researchers have created a novel prototype system that uses quantum technology and LiDAR to overcome these difficulties.

A research team from the UK's Nottingham Trent University, the Australian National University and the University of New South Wales Canberra has developed a display prototype that could replace the LCD panels common to many of today's big-screen TVs.

Researchers have developed an ultra-small, ultra-thin LiDAR device that splits a single laser beam into 10,000 points covering an unprecedented 180° field of view. It's capable of 3D depth-mapping an entire hemisphere of vision in a single shot.

Mapping the inside of cramped, difficult-to-reach areas can be helpful to people such as plant operators, but drones flown in such places could easily crash. The LiDAR- and cage-equipped Elios 3 quadcopter was designed with that challenge in mind.

A landmark study is reporting the discovery of nearly 500 ancient monuments in Mexico using airborne laser mapping. The newly discovered sites are thought to date back at least 2,500 years, in between the Olmec and Maya civilizations.

DJI is bringing its stabilization know-how to cinematic content creation with the launch of the Ronin 4D system, which rolls a new full-frame gimbal camera, 4-axis stabilization, a LiDAR focusing, and video transmission/control into a single package.

Autonomous vehicles operate in a complex environment, and recognizing traffic signs is an important part of that. A new microstructured material reflects light in rainbow rings, which can make traffic signs easier for computer vision systems to read.

Samsung is claiming a few world firsts with its latest robot vacuum cleaner. The Jet Bot AI+ is said to be the first to feature an active stereo-type 3D sensor for object detection, and the first equipped with Intel AI for object recognition.

Airtext has released a simple laser altimeter for small aircraft to make approaches and landings safer. The app-controlled Land-DAR (Land Distance and Ranging) is configured through an app and calls out altitudes as the aircraft descends.

Airbus is expanding the capabilities of its Flightlab helicopter designed to test out next-generation aviation technologies, by incorporating some advanced hardware geared toward autonomous flight, including LiDAR sensors from Luminar.

Self-driving cars typically use both LiDAR and radar to detect obstacles on the road ahead, yet neither system is adept at identifying vehicles through fog. Now, though, engineers have discovered that radar is good at the task if it's "doubled up."
