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

依据光声效应产生的超声波具有波的特性,借鉴光学成像理论,提出了一种新的光声信号成像模式-利用声透镜直接成像。以声场复振幅来描述声场分布,根据基尔霍夫衍射理论,从理论上推导了声透镜的脉冲响应,并通过实验得到了生物组织的功能成像。 相似文献
