Paper Abstract

The irradiance at Talbot images in tapered gradient-index (GRIN) media for ideal periodic objects is presented. The effects on Talbot images due to off-axis illumination and finite object dimension are considered. 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 apperture diffractive effect on the Talbot images as well as the walk-off effect.
