Hello all:

 

what's the method to calculate the SNR for two-photon microscopy?

 

Thanks

Sarah

Hi Sarah,
    I used an easy way to measure SNR in two-photon microscopy:
P Xi, Y Andegeko, LR Weisel, VV Lozovoy, M Dantus - Optics
Communications, 2007 - Elsevier "Greater signal, increased depth, and
less photobleaching in two-photon microscopy with 10fs pulses"

    Keep in mind that SNR has no relationship with how you obtain your
image -- no matter it is confocal, wide-field, or multiphoton.
    Thank you!

A fairly detailed account about noise and how to measure it can be found here:
