Abstract [en]
In this report, remote sensing with Light Detection and Ranging (LIDAR) was demonstrated. In particular, a Frequency Modulated Continuous Wave (FMCW) LIDAR was used to reconstruct the motion of a moving target. Measurements were performed at the single photon level using a Superconducting Nanowire Single Photon Detector (SNSPD) and velocity and distance time series were reconstructed. The limitations of the technique were investigated by comparing three different targets. Furthermore, vibration sensing was performed where the vibrational modes were successfully reconstructed for a speaker. Additionally, multi-pitch decomposition was demonstrated and the Signal to Noise Ratio (SNR) - dependency on speaker frequency was studied.
