A METHOD FOR CHARACTERIZING OPTICAL PROPERTIES OF A NON-LINEAR IMAGING DEVICE USING HARMONIC GENERATION NANOPROBES

摘要

Method for characterizing at least one optical property of any non-linear imaging device, the method comprising: exciting at at least one arbitrary wavelength selected in a range of excitation wavelengths a calibration tool (3) comprising a predefined distribution of harmonic generating nanoparticles (6); acquiring at least one optical signal generated by the calibration tool in response to this excitation; and processing the at least one signal to generate therefrom data useful to characterize said at least one optical property of the device, said at least one optical property being preferably selected among a spatial resolution of the imaging device, a laser beam or optics alignment, a chromatic aberration and a field curvature.
