From: Towards autonomous robotic THz-based in vivo skin sensing: the PicoBot
Comparison between the handheld system and the PicoBot for the stability during skin scanning using the THz response. (a) Averaged Impulse function and variation over the four repeated measurements of the volar forearm by O1, O2 and PB. (b) Standard deviations (STD) of the averaged impulse functions in (a). Standard deviations (STD) of the (c) amplitude and (d) phase of the averaged THz Impulse Functions (IF) over the frequency domain, with different operators (O1 and O2) and the PicoBot (PB).
