We demonstrate a sum frequency generation (SFG) holographic imaging method by integrating the capabilities of holography and SFG spectroscopy. SFG can probe the molecular vibrational resonance in non-centrosymmetric media. Holographic recording can capture both the amplitude and the phase of the SFG signal, thus leading to label-free spectroscopic three-dimensional imaging.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the conference proceedings. They include the speaker's narration along with a video recording of the presentation slides and animations. Many conference presentations also include full-text papers.
