The majority of driver assistance systems and completely autonomous vehicles currently use solid-state systems, known as LIDAR systems to measure distances and detect obstacles: The abbreviation LIDAR stands for "light detection and ranging" and describes a method used to measure the environment using the reflection of emitted laser beams. The Fraunhofer Institute for Production Technology IPT in Aachen, Germany, has developed a system for the automated assembly of solid-state LIDAR systems so that such systems can soon be made available to the automotive industry at low cost.
Alignment of the optical components with micrometer accuracy
The prototype was integrated into a basic machine manufactured by the project partner Aixemtec GmbH and put into operation together with Ibeo Automotive Systems GmbH, worldwide technology leader in LIDAR sensors.
The system, consisting of the assembly system integrated into the basic Aixemtec machine, is now able to align an optical system consisting of two lenses, a laser light source and a sensor with high precision.
The Aachen researchers equipped an individually developed passive assembly system based on the 3D "Commander 6" manipulator with newly developed measuring technology to test the alignment of the mounted lenses and chips to each other during the assembly process.
The particular challenge was to align and connect the optical elements with micrometer precision.
Assembly plant on-stream within only six months
The Fraunhofer IPT and Aixemtec managed the development and installation of the system for Ibeo within just six months of the start of the project.
By using standard components from the partners' portfolio, Ibeo is now preparing to deliver the first small series of its new LIDAR systems to developers and customers.
The prototype of the system is so flexibly designed that it can also be used for comparable similar tasks, for example for cameras or other imaging or projecting optical systems.

Styrofoam or copper - both materials have very different properties with regard to their ability to conduct heat. Scientists at the Max Planck Institute for Polymer Research (MPI-P) in Mainz and the University of Bayreuth have now jointly developed and characterized a novel, extremely thin and transparent material that has different thermal conduction properties depending on the direction. While it can conduct heat extremely well in one direction, it shows good thermal insulation in the other direction.
Thermal insulation and thermal conduction play a crucial role in our everyday lives - from computer processors, where it is important to dissipate heat as...
In order to advance the transfer of research developments from the field of quantum sensor technology into industrial applications, an application laboratory is being established at Fraunhofer IAF. This will enable interested companies and especially regional SMEs and start-ups to evaluate the innovation potential of quantum sensors for their specific requirements. Both the state of Baden-Württemberg and the Fraunhofer-Gesellschaft are supporting the four-year project with one million euros each.
The application laboratory is being set up as part of the Fraunhofer lighthouse project »QMag«, short for quantum magnetometry. In this project, researchers...

Researchers from the University Hospital Zurich, ETH Zurich, Wyss Zurich and the University of Zurich have developed a machine that repairs injured human livers and keep them alive outside the body for one week. This breakthrough may increase the number of available organs for transplantation saving many lives of patients with severe liver diseases or cancer.
Until now, livers could be stored safely outside the body for only a few hours. With the novel perfusion technology, livers - and even injured livers - can now...
A balloon-borne scientific instrument designed to study the origin of cosmic rays is taking its second turn high above the continent of Antarctica three and a half weeks after its launch.
SuperTIGER (Super Trans-Iron Galactic Element Recorder) is designed to measure the rare, heavy elements in cosmic rays that hold clues about their origins...
