摘要 The nonlinear effect of two-photon excitation on the imaging property of two-photonconfocal microscopy has been analyzed by the two-photon fluorescence intensity transfer functionderived in this paper. The two-photon fluorescence intensity transfer function in a confocal micros-copy is given. Furthermore the three-dimensional point spread function (3D-PSF) and thethree-dimensional optical transfer function (3D-OTF) of two-photon confocal microscopy are de-rived based on the nonlinear effect of two-photon excitation. The imaging property of two-photonconfocal microscopy is discussed in detail based on 3D-OTF. Finally the spatial resolution limit oftwo-photon confocal microscopy is discussed according to the uncertainty principle.
