Abstract
We demonstrated a molecular spectroscopic imaging method by integrating the capabilities of holography and vibrational sum frequency generation (SFG) spectroscopy. SFG is a second-order nonlinear optical process that can probe molecular vibration resonance. SFG also poses stringent requirement of noncentro-symmetry, useful for suppressing interfering contributions in a complex environment. Further, holographic detection captures a wide-field complex SFG signal including both the amplitude and phase information, thus enabling new opportunities for three-dimensional label free imaging.
