Paper Abstract

Fluorescent nanobeads embedded in agarose and skin biopsies were used to optically characterize spatial and temporal resolution of multiphoton laser scanning devices (MPLSD). Optical sections based on two-photon excited bead fluorescence have been performed at various sample depths. Three-dimensional reconstruction of the image stacks allowed determination of the point spread function. Using calculated point spread functions to apply deconvolution procedures (e.g. Huygens software), the visualization and hence the interpretation of intradermal structures, such as extracellular matrix components in 150 μm tissue depth, was improved.
