EXPERIMENTAL self-driving cars continue to make regular forays onto the roads. After a trial in Pittsburgh, Uber, a taxi-hailing-app company, launched several of its “autonomous” vehicles onto the ...

San Jose, California, firm NeoPhotonics has revealed details of a new laser aimed at frequency-modulated continuous wave (FMCW) lidar for applications in the automotive and industrial machine vision ...

Lidar sensors work by bouncing laser light off surrounding objects to produce a three-dimensional “point cloud.” The first modern three-dimensional lidar was created for the 2005 DARPA Grand Challenge ...

A research team has designed a new approach that could lead to underwater imaging lidars that are much smaller and more efficient than the current full-size systems. The new technology would allow ...

Lunar Reconnaissance Orbiter’s Lunar Orbiting Laser Altimeter has produced detailed maps of the Lunar South Pole, including where water ice appears to fill the bottoms of permanently shadowed craters.

Light detection and ranging (LiDAR) sensors are moving from niche scientific and space applications to mass-market adoption to deliver 3D data with depth resolution in advanced driver-assistance ...

Interfacing laser driver circuits with commercially available laser diodes at high data rates can be a complicated and frustrating task. This application note is intended to briefly address this topic ...

Understanding the different lidar (light detection and ranging) concepts is important when designing lidar subsystems for the auto and truck industry. They are similar to radars but use lasers rather ...

If there’s one lesson to be learned from [Aled Cuda]’s pulsed laser driver, it’s that you can treat the current limits on electronic components as a suggestion if the current duration is measured in ...

Researchers at Georgia Tech significantly reduce system size, promising new reconnaissance and mapping applications. The lightweight lidar prototype uses a green laser to penetrate water at depth.
