Simultaneous Multifrequency Demodulation for Single-Shot Multiple-Path ToF Imaging — Indirect Time-of-Flight (iToF) sensors measure the received signal's phase shift or time delay to calculate depth. In realistic conditions, however, recovering depth is challenging as reflections from secondary scattering areas or translucent objects may interfere with the direct reflection, resulting in inaccurate 3D estimates. We propose a new measurement concept including a single-shot on-chip multifrequency demodulation method with periodically-repeated ultrashort-pulsed illumination using a — Citations: 9.
An Experimental Testbed for the Performance Evaluation of Optical Time Difference of Arrival Based Indoor Positioning — Time Difference of Arrival (TDoA) based Visible Light Positioning (VLP) and Optical Wireless Positioning (OWP) offer considerable potential over conventional Received Signal Strength (RSS) methods. The current state of the art in TDoA OWP is however limited concerning experimental assessments, mainly focusing on simulations. This work presents experimental TDoA measurements in a proof-of-concept setup. The measurement results demonstrate a 95th percentile accuracy of 5.3 cm in a 50×50 cm area, i — Citations: 8.
