MEASUREMENTS OF LIGHT FIELDS EMERGING FROM FINE AMPLITUDE GRATINGS

High resolution amplitude and phase of light fields emerging from a 2-μm-period amplitude grating are measured for different wavelengths. The amplitude gratings lead to highly periodic patterns caused by the Talbot effect. Such patterns reach periodicities of a fraction of the grating period. We discuss the effect of wavelengths and the number of diffraction orders participating in the imaging.
