Abstract:
Handheld, lightweight laser rangefinders provide distance measurements with millimetric precision and distances up to several hundred feet via the time-of-flight method. The time-of-flight to a target and back can be measured either directly or indirectly by evaluating the phase of an intensity modulated laser beam. To achieve millimeter distance resolution, roundtrip times have to be resolved with an accuracy of a few picoseconds. As the application is focused on non-military use in civil engineering, construction and DIY, a low-cost system is crucial. Photon counters integrated in CMOS technology allow for cost and size reduction over current systems based on avalanche photodiodes and high precision optics.
Biography:
Andreas Eisele studied Electrical Engineering and Information Technology at the University of Karlsruhe, Germany (B.S. equivalent 2007). He received his Master’s degree in Optics from the University of Central Florida, USA in 2008, where he spent time with the Center for Research and Education in Optics and Lasers (CREOL) on a Fulbright scholarship working on OFDM in Optical Fiber Communications. Currently, he is working towards his PhD as a research assistant at Robert Bosch GmbH and the Institute of Photonics and Quantum Electronics (IPQ) at the Karlsruhe Institute of Technology (KIT). His present research interest is focused on laser optical measurement and photon counters. Further interests include German and European Patent law.
