A LiDAR device the size of a finger now available

A nanophotonics-based LiDAR technology developed by a POSTECH research team was presented as an invited paper in Nature Nanotechnology, the leading academic journal in the field of nanoscience and nanoengineering.

3D holographic head-up display could improve road safety

Researchers have developed the first LiDAR-based augmented reality head-up display for use in vehicles. Tests on a prototype version of the technology suggest that it could improve road safety by 'seeing through' objects ...

Scientists achieve single-photon imaging over 200 kilometers

A research team led by Professor Pan Jianwei and Professor Xu Feihu from University of Science and Technology of China achieved single-photon 3D imaging over 200 km using high-efficiency optical devices and a new noise-suppression ...

Lunar cave explorer

What might look like a dangling hamster ball is actually a robotic sphere to explore the depths of lunar caves.

Radar-lidar ratio: prospective method in cirrus clouds research

Recently, a team of researchers led by WANG Zhenzhu from the Anhui Institute of Optics and Fine Mechanics (AIOFM) of the Hefei Institutes of Physical Science (HFIPS), together with their international collaborator from the ...

LIDAR

LIDAR (Light Detection And Ranging, also LADAR) is an optical remote sensing technology that can measure the distance to, or other properties of a target by illuminating the target with light, often using pulses from a laser. LIDAR technology has application in geomatics, archaeology, geography, geology, geomorphology, seismology, forestry, remote sensing and atmospheric physics, as well as in airborne laser swath mapping (ALSM), laser altimetry and LIDAR contour mapping.

The acronym LADAR (Laser Detection and Ranging) is often used in military contexts. The term "laser radar" is sometimes used, even though LIDAR does not employ microwaves or radio waves and therefore is not radar in the strict sense of the word.
