Correlative images can be obtained using different multiphoton schemes such as 2PEF, 3PEF, and Third harmonic generation (THG), in parallel (since the corresponding wavelengths are different, they can be easily separated onto different detectors). A multichannel image is then constructed. 3PEF is also compared to 2PEF: it generally gives a smaller degradation of the signal-to-background ratio (SBR) with depth, even if the emitted signal is smaller than with 2PEF. Web14 Mar 2024 · Enter the three-photon version! Now the even lower energy of the photons makes tissue more optically transparent, though for activation of the fluorescent protein, three photons have to hit it simultaneously. But that’s part of the beauty of the system—the visual “noise” also goes down.
