摘要

Irradiance at fractional and integer Talbot images in tapered gradient-index (GRIN) media for ideal periodic objects is presented. Talbot effect for off-axis illumination and finite object dimension is investigated. Results have been applied to a hybrid structure composed by a divergent linear tapered 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.
