Gj. Brakenhoff et al., REAL-TIME 2-PHOTON CONFOCAL MICROSCOPY USING A FEMTOSECOND, AMPLIFIEDTI-SAPPHIRE SYSTEM, Journal of Microscopy, 181, 1996, pp. 253-259
The bilateral imaging approach known from confocal applications operat
ing in the line mode was used to realize real-time two-photon imaging.
It is shown that the sectioning inherent to two-photon imaging could
be improved by the introduction of a confocal lie aperture in the imag
ing path. Using a high-power, low-repetition-rate amplified Ti:sapphir
e system, various biological objects were visualized including live bo
ar sperm.
