lidar for autonomous vehicles debuted in 2007 as an enabling sensor technology for robotaxis and robotruck development. Within the last five years, however, the technology has trended toward broader...

As society considers a future with autonomous vehicles (AVs), lidar continues to be a hot topic. Since 2016, there has been huge interest in automotive lidar, which has resulted in investments and...

There are a number of applications for which 3D sensing is rapidly emerging as a critical sensing modality. 3D and 4D sensors are arising in autonomous vehicle applications because they are propelled...

The history of radar (radio detection and ranging) dates back to the 1880s when renowned German physicist Heinrich Hertz showed that radio waves were reflected by metallic objects. Based on the...

Over 50 years ago, light detection and ranging technology (lidar) found its earliest applications in military targeting and meteorology research, and famously, in mapping the surface of the moon in...

The defense industry, with its high performance and rugged environmental requirements, has long driven development of state-of-the-art technology platforms that have trickled down into commercial and...

The technologies we use in our everyday activities to monitor the world around us — to develop new medicines or to produce the materials we use to build homes, offices, and factories —...

The dream of fully autono­mous, driverless cars remains just that for now — a vision of a future that will require considerable effort from engineers and programmers to realize. But other,...

First conceived by editors of Scientific American magazine, the dream of self-driving cars — known today as autonomous vehicles (AVs) — recently passed its 100-year anniversary. With the...

The accurate measurement of relative air speed, temperature and pressure is essential for the flight control system to operate safely and economically within the operational envelope and set flight...

As anyone who has ever worked with an alexandrite laser can attest, its lasing medium demands respect. “It has about every problem a laser engineer can imagine,” said Josef Höffner,...

The growing importance of laser-based remote sensing instruments to NASA scientists and space mission designers is not surprising. Lasers offer clear advantages over passive and active radio-wave...

Digitalization of the world requires detection tools able to recognize objects and precisely measure distances quickly. lidar-based monitoring systems are a key part of this current technological...

lidars provide point cloud distribution — to represent the 3D environment — using the backscattering of a laser beam from the target surface. They have long been used for purposes of...

For many decades, lidar has been a successful technology for traffic monitoring and speed control. Self-driving transport vehicles in factory halls even use it for navigation. During all this time,...

Two different optical technologies — one already deployed, the other still on the drawing board — promise to ease autonomous vehicle integration. lidar, the optical analog to radar, is...

Rescue agencies the world over have rallied together in a bid to bring relief to the thousands of people left injured, homeless and without food or sanitation in the wake of the Haiti earthquake,...

For light detection and ranging (lidar) scanners, the returns are in – and they’re good. Innovations have made lidar scanners, which emit laser pulses and capture the returning light to determine...

Imaging lidar sensors are one of the primary components in systems used for perception tasks in autonomous vehicles. The 3D data generated by lidar while a vehicle is in motion is considered useful...

Tech advancements, especially in disruptive technologies, often drive down crooked, poorly mapped roads. AT&T’s Picturephone was introduced to huge fanfare at New York’s 1964...
