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.

Scientists at the Fraunhofer Institute for Laser Technology ILT have come up with a striking new addition to contact stamping technologies in the ERDF research project ScanCut. In collaboration with industry partners from North Rhine-Westphalia, the Aachen-based team of researchers developed a hybrid manufacturing process for the laser cutting of thin-walled metal strips. This new process makes it possible to fabricate even the tiniest details of contact parts in an eco-friendly, high-precision and efficient manner.

An international research team with Prof. Cornelia Denz from the Institute of Applied Physics at the University of Münster develop for the first time light fields using caustics that do not change during propagation. With the new method, the physicists cleverly exploit light structures that can be seen in rainbows or when light is transmitted through drinking glasses.
Modern applications as high resolution microsopy or micro- or nanoscale material processing require customized laser beams that do not change during...
