“…La alfombra de Talbot es el sistema de patrones de interferencia formados en la región cercana a la rejilla, cuyos máximos principales son altamente contrastados y de dimensiones menores a las de las aberturas de la rejilla (Chapman et al, 1995;Case et al, 2009). Por este motivo, el registro de dichos patrones es de mucho interés para la fabricación de dispositivos fotoelectrónicos basados en nano−filamentos (nano−wires), una tecnología orgánica que intenta superar a la de silicio (Iannotta & Toccoli, 2003).…”

El aparato matemático empleado para la predicción de los patrones de interferencia es similar y se basa en la superposición de funciones de onda. No obstante, mientras que en el caso de la luz la superposición de ondas es un principio fenomenológico que conduce a explicaciones físicas, en el caso de la materia, las funciones de onda no tienen significado físico, por lo que su superposición no conduce a explicaciones fenomenológicas. Así, fenómenos físicos análogos no se explican con base en causas naturales comunes y necesarias, como lo establecen las dos reglas de filosofía natural de Newton vigentes para el análisis de resultados experimentales. En este trabajo se proponen fundamentos conceptuales para una teoría basada en un nuevo principio físico de interferencia, tanto para luz como para la materia, que supera tales limitaciones y se ajusta a las reglas filosóficas de Newton.PALABRAS CLAVE: Interferencia, ondas, partículas, coherencia.ABSTRACT: Interference of light and matter is quite differently dealt, although in both cases it is produced by experimental arrangements with the same settings on a different scale, that deliver results of similar morphology, called interference patterns. The mathematical apparatus used for the prediction of the interference patterns is similar and based on the superposition of wave functions. However, while in the case of light the wave superposition is a phenomenological principle leading to physical explanations, in the case of matter, the wave functions do not have physical meaning, so that their superposition does not lead to phenomenological explanations. So, analogous physical phenomena are not explained on the basis of common and necessary natural causes, as established by two Newton's rules of natural philosophy still valid for the analysis of experimental results. In this paper, conceptual foundations for a unified theory based on a new a Castañeda, R. (2016).

Testing the Clauser-Horne-Shimony-Holt inequality using observables with arbitrary spectrum

The Clauser-Horne-Shimony and Holt inequality applies when measurements with binary outcomes are performed on physical systems under the assumption of local realism. Testing such inequalities in the quantum realm usually involves either measurements of two-valued quantum observables or pre-defining a context dependent binning procedure. Here we establish the conditions to test the Clauser-Horne-Shimony and Holt inequality using any quantum observable. Our result applies to observables with an arbitrary spectrum and no prior knowledge of their underlying Hilbert space's dimension is required. Finally, we demonstrate the proposed general measurement strategy, that can be seen as positive operator valued measurements performed on the system, using the formalism of modular variables applied to the transverse degrees of freedom of single photons.

“…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.
