Abstract
Irradiance at fractional and integer Talbot images in tapered gradient-inde x (GRIN) media for ideal periodic objects is presented. Talbot effect for o ff-axis illumination and finite object dimension is investigated. Results h ave been applied to a hybrid structure composed by a divergent linear taper ed GRIN medium and a sinusoidal amplitude grating to show transverse shift and finite-aperture diffractive effect on the Talbot images as well as the walk-off effect.
