The invention relates to a system for carrying out fibered multiphoton microscopic imagery of a sample (10) for use in endoscopy or fluorescence microscopy. This system comprises: a femtosecond pulsed laser (1, 2) for generating a multiphoton excitation laser radiation; an image guide (8) comprised of a number of optical fibers and permitting the sample to be illuminated by a point-by-point scanning in a subsurface plane; pre-compensating means (4) for pre-compensating for dispersion effects of the excitation pulses in the image guide (8), these means being situated between the pulsed laser and the image guide (8); scanning means for directing, in succession, the excitation laser beam in a fiber of the image guide, and; in particular, an optical head (9) for focussing the excitation laser beam exiting the image guide in the sample (10). |
