> Pointmedia is making its self-developed content management system (CMS) Holopipe available to the general public for the first time. The app was developed for Android and iOS and converts 3D content into holograms. This allows users to interact with virtual objects in the real world. Robot appears as a 3D model on the desk

Holograms can help industrial designers to verify their product in their original size.

Researchers at the University of Münster have developed a molecular phototransistor that works much more efficiently than comparable transducers. Phototransistors are used, for example, in communication technology or in electronic imaging.

US and Swiss researchers use laser beam technology to transport the energy required by drones into the air. He meets solar cells that generate electricity for the on-board batteries. Military and civilian missions are possible.

Drone flies over a lake and is illuminated by lasers from the ground.

Solar cells at the bottom of the drone are to catch the laser beams.

Researchers in the US and Switzerland have independently developed drone chargers. The special feature: The on-board batteries are charged (more…)

Researchers at the Vienna University of Technology have developed a way to produce laser frequency combs simpler and more robust than before. This enables chemical analyzes in the smallest of spaces.

Symbols Laser

Lasers can be used, for example, to measure molecules in gases.

An ordinary laser has only one color whose photons have the same wavelength. In a frequency comb, the light, on the other hand, consists of many different frequencies (more…)

Why can we wirelessly surf and make calls, but need a charging cable as soon as the battery is empty? Researchers at the University of Washington have probably asked themselves this question and now present a laser that can charge smartphones at a distance of up to 12 meters.

The laser loads the smartphone without the human eye seeing the rays. For illustrative purposes, red lines were used here.

It should be a milestone for more safety for motorcyclists. But the project of the motorcycle helmet Skully was a disaster – especially because the founders could not handle the sudden blessing.

Skully Helmet

The developers of the helmet Skully Indiegogo set a target of $ 250,000. They finally collected more than $ 2 million.

Researchers have succeeded in making one of the most accurate tools even more accurate. They developed a laser beam that can be used to improve optical atomic clocks.

Lasers are used in industry for machining workpieces, such as in the automotive industry.

Where are the biggest devastations? Can you still get through with the ambulance? Usual maps are of little use after major disasters. Roads and bridges can be destroyed, paths are spilled. Now the DLR has tested a technique to insert aerial images of drones live into maps that can be used by the groundhandlers.

At least for a month, avocados and sweet potatoes are allowed out of the plastic packaging at Rewe. The retail giant simply lays the labels, which otherwise stick to the packaging, directly into the bowl – completely free from residues or damage. Plastic packaging can therefore be superfluous.

In a test run, Rewe uses a low-energy laser to mark organic vegetables like these sweet potatoes. If this is well received by customers, Rewe wants to dispense with the plastic packaging for organic vegetables.

Wow! What looks like a banal desk light is actually a modern version of Aladdin’s magic lamp. It can project images into the environment that fool the viewer 3D. And without, that he needs a virtual reality glasses. How does the Hololamp invention accomplish this?

The Hololamp can project images into the environment that give the viewer three-dimensionality.
