Fast LiDAR technology published in Nature Photonics

Professor Sebastian 'Nino' Karpf from the Institute of Biomedical Optics (BMO) has developed a novel system for LiDAR that enables fast spatial imaging in 3D. High speeds are achieved by using a novel inertia-free spectral scanning method. This work was conducted in cooperation with researchers from the University of California, Los Angeles (UCLA).

LiDAR is the optical alternative to RADAR. By means of laser light a three-dimensional detection of space can be achieved and is used among other things in autonomous vehicles or in robotics. In the recently published publication "Time-stretch LiDAR as a spectrally scanned time-of-flight ranging camera" in Nature Photonics, a system is described that enables fast, inertia-free detection in two spatial dimensions. This independence from inertia-limits is a decisive advantage over mechanical scanning systems and is achieved by a spectral approach and additional time-encoding. The spectro-temporal method in combination with newly developed laser technology is now employed in this time-stretch LiDAR system and enables very fast acquisition speeds.

Sebastian 'Nino' Karpf is a Juniorprofessor for translational biomedical photonics at the Institute of Biomedical Optics (BMO) at the University of Lübeck since April 2018. The Juniorprofessorship was established as part of the Schleswig-Holstein Excellence Chair Program (SH-Chair Prof. Robert Huber) and the Excellenccluster "Precision Medicine for Inflammation (PMI)" (DFG - EXC 2167). In these programs, novel optical methods are researched and subsequently applied to biomedical inflammation research.
