The novel field-resolved microscopy scheme of Quantum-probe Field Microscopy (QFIM) utilized fluorescence quanta to images local THz-electric waveforms [1]. In this contribution, we discuss the basis of the ultrafast microscopy scheme and the recovery of multi-Terahertz signals from fluorescence data. We elaborate fundamental aspects of time-domain sampling of electric waveforms and different strategies to recover response functions of systems under investigation.
