“…The single exposure imaging method could be applied for rapid characterization of sources in metrology, where the wave propagation image over near-and far-fields is used for the analysis [20]. The method also enables printing Talbot carpets on photoresist samples using an interference lithography technique.…”

“…While fractional Talbot patterns are cross-sections of intensity distribution orthogonal to the light propagation axis, patterns at the plane containing the optical axis are referred to as a "Talbot carpet" or "carpet of light" [6]. In our interest, the visualization of the optical Talbot carpet is usually performed by computer integration of images recorded by digital camera at different distances from the grating [17][18][19][20]. However, in order to obtain the image of the Talbot carpet, a large number of such high-resolution images are required.…”

In this paper, we demonstrate a self-imaging technique that can visualize longitudinal interference patterns behind periodically-structured objects, which is often referred to as Talbot carpet. Talbot carpet is of great interest due to ever-decreasing scale of interference features. We demonstrate experimentally that Talbot carpets can be imaged in a single exposure configuration revealing a broad spectrum of multi-scale features. We have performed rigorous diffraction simulations for showing that Talbot carpet print can produce ever-decreasing structures down to limits set by mask feature sizes. This demonstrates that large-scale pattern masks may be used for direct printing of features with substantially smaller scales. This approach is also useful for characterization of image sensors and recording media.

Abstract:We analyze the far field and near field diffraction pattern produced by an amplitude grating whose strips present rough edges. Due to the stochastic nature of the edges a statistical approach is performed. The grating with rough edges is not purely periodic, although it still divides the incident beam in diffracted orders. The intensity of each diffraction order is modified by the statistical properties of the irregular edges and it strongly decreases when roughness increases except for the zero-th diffraction order. This decreasing firstly affects to the higher orders. Then, it is possible to obtain an amplitude binary grating with only diffraction orders -1, 0 and +1. On the other hand, numerical simulations based on Rayleigh-Sommerfeld approach have been used for the case of near field. They show that the edges of the self-images are smoother than the edges of the grating. Finally, we fabricate gratings with rough edges and an experimental verification of the results is performed.

“…Some works about cancellation or pseudocancellation of the Talbot effect with polychromatic light [8] and in double-grating systems [9] have been published. When the Talbot effect is canceled, then the intensity distribution is nearly independent of the distance from the grating to the observation plane.…”

Continuous self-imaging regime with a double-grating mask

We analyze the Talbot effect produced by a mask composed of two diffraction gratings. Combinations with phase and amplitude gratings have been studied in the near-field regime. For a two-phase-gratings configuration, the Talbot effect is canceled, even when using monochromatic light; that is, the intensity distribution is nearly independent of the distance from the mask to the observation plane. Therefore, the mechanical tolerances of devices that use the Talbot effect may be improved. In addition, the spatial frequency of the fringes is quadrupled, which improves the accuracy of devices that employ this mask. An experimental verification for the best case two phase gratings, has also been performed, validating the theoretical results.
