For years, he had been using airborne laser sensors known as Lidar (Light Detection And Ranging) to map
and commissioned the National Center for Airborne Laser Mapping (NCALM) Â to fly a twin-engine plane backwards
and forwards over the tree-tops firing pulses of laser light at the ground below.
All shoot thousands of pulses of laser light and then use sensors to detect any reflections.
Crucially, some of the laser light is also able to penetrate vegetation. So, in the case of areas covered in a forest canopy
But not everyone is convinced by the laser revolution. Archaeologists like Rosemary Joyce, a professor of Mesoamerican archaeology at the University of California, Berkeley,
a UV laser is beamed onto a very thin layer of photopolymer causing it to harden.
the platform is lowered so the next layer can be traced out and hardened by the laser. Layer by layer, material is hardened by the laser until a complete object has been printed
and can be removed from the vat of photopolymer. Stereolithographic printers remain one of the most accurate types of hardware for fabricating 3d objects.
Fused deposition modelling (FDM) Selective laser sintering (SLS) Selective laser melting (SLM) Multi-jet modelling (MJM) Clearly this is an industry hung up on three letter acronyms.
including etching identification codes on produce with lasers or micro-percussion markers that make tiny indents.
It s surmounted by a spinning laser turret and knobbed with cameras, radar, antennas, and G. P. S. It looks a little like an ice-cream truck, lightly weaponized for inner-city work.
His team spent twenty-eight days laser-scanning the Mojave to create a computer model of its topography;
The lasers on the roof scanned the area around the car, while the camera looked farther ahead.
It also compared its camera images with its laser scans, so that it could tell what flat terrain looked like from a distance#nd therefore drive a lot faster.#
Arguably the most important outcome of the DARPA field trials was the development of a robust and reliable laser range finder.
His company, Velodyne, makes a unit that packs 64 lasers in a turret that typically rotates at 600 rpm,
they don t have the laser focus on a single segment of the adoption curve at one time, much less the correct segment.
In 2007 Evil Mad Scientist Laboratories introduced the Candyfab 4000 a DIY printer based on a modified selective laser sintering technique.
And we DID in fact land on the moon the proof is in the retroreflectors that we can use on a regular basis to measure (with extreme precision) with lasers the distance between Earth and the moon.
Arguably the most important outcome of the DARPA field trials was the development of a robust and reliable laser range finder.
His company Velodyne makes a unit that packs 64 lasers in a turret that typically rotates at 600 rpm continuously strafing the landscape with 64 separate beams.
Terrill uses a laser pointer to indicate the newest find. The hard edges provide bright scatter he says.
the Nanovelcro CTC chip laser capture microdissection and whole exome sequencing said Yi-Tsung Lu MD a postdoctoral scientist at the Cedars-Sinai Samuel Oschin Comprehensive Cancer
Next laser capture microdissection technology allows the scientists to selectively cut out and pick up the CTCS from the Nanovelcro Chip virtually eliminating any trace of any contamination from white blood cells
According to Domingue the light-scattering properties of the beetle's shell--which the team experimentally demonstrated using a white laser--made the nano-bioreplicated decoys more lifelike and therefore more attractive to males than the non-textured 3d printed decoy.
and Masayoshi Tonouchi of Osaka's Institute of Laser Engineering discovered a way to detect
Hitting the combined material with femtosecond pulses from a near-infrared laser prompted the indium phosphide to emit terahertz back through the graphene.
The laser gradually removes oxygen molecules from the graphene changing its density and we can see that Kono said.
Laser pulses generated coherent bursts of terahertz radiation through a built-in surface electric field of the indium phosphide substrate that changed due to charge transfer between the graphene and the contaminating molecules.
low cost laser technique to improve properties and functions of nanomaterialsby â#drawingâ##micropatterns on nanomaterials using a focused laser beam scientists could modify properties of nanomaterials for effective applications in photonic and optoelectric applications.
The research team fabricated a photodetector using laser modified Mos2 film and demonstrated the superior performance of Mos2 for such application.
This is the first observation of such a laser-modified behaviour from the mesoporous silicon nanowires to be reported.
 The researchers systematically studied the laser-induced modification to gain insights into establishing control over the optical properties of the mesoporous silicon nanowires.
The research team demonstrated that the micropatterns created at a low laser power are invisible under bright-field optical microscope
--and have a laser-like focus on productivity. Innovation lies at the heart of society. Â Science and technology research lie at the heart of innovation.
which appraisers have placed traditionally great importance on as a way to authenticate objects) can be copied by lasers with great precision.
