Descripción del proyecto
Nuevas técnicas de procesamiento óptico revolucionan la imagenología y la metrología
Se vislumbra un ámbito de investigación nuevo y prometedor que combina la óptica no lineal ultrarrápida y las imágenes computacionales. Mediante la combinación de componentes ópticos integrados y fibrosos, será posible explorar nuevas dinámicas no lineales multimodo y dependientes de datos de entrada a través de esquemas de aprendizaje automático especializados. Este es el objetivo del proyecto STREAMLINE, financiado con fondos europeos, que constituye un ambicioso programa multidisciplinario para impulsar el desarrollo de las fuentes fotónicas inteligentes. Los sistemas fotónicos actuales se basan principalmente en complejos procesos ópticos no lineales que constituyen la base de aplicaciones exigentes que abarcan el desarrollo avanzado de fuentes de luz, la metrología y la imagenología. Sin embargo, las formas de controlar los fenómenos y las interacciones no lineales son bastante limitadas, mientras que llegar a los entornos ideales para una aplicación específica puede ser un reto. Para cambiarlo, en STREAMLINE se ofrecerán técnicas de procesamiento óptico revolucionarias que harán posibles métodos innovadores de imagenología y metrología.
Objetivo
Modern photonic systems increasingly rely on complex nonlinear optical processes at the foundation of demanding applications spanning advanced light source development, metrology and imaging. Importantly, current flagship imaging systems are based on nonlinear light-matter interactions provided by specialized lasers requiring complex operation and lacking tunability: means of controlling nonlinear phenomena and interactions are restricted, and reaching the ideal settings for a specific application can prove extremely challenging.
In this context, optical excitations can be inefficient (with e.g. excessive power or spectral coverage) and versatile means to drive coherent control of light properties are highly sought-after, for they provide the main building blocks for advanced imaging techniques. However, such control is currently constrained to few degrees of freedom provided by complex components ultimately hindering the accessible optical parameter space.
The realization of versatile, efficient and practical optical sources in compact forms would thus represent a fundamental revolution.
STREAMLINE constitutes an ambitious multidisciplinary program aiming to push forwards the development of 'smart photonic sources' for the creation of a promising new research field merging ultrafast nonlinear optics and computational imaging. The envisioned architecture, combining integrated and fibered components, will explore new multimode and input-dependent nonlinear dynamics via dedicated machine-learning schemes.
Together with suitable monitoring techniques, fully reconfigurable and tailored optical wavepackets (with ‘on-demand’ spectral, temporal and spatial properties), will be exploited towards disruptive nonlinear imaging and metrology techniques. Besides providing user-friendly operation with improved performances, blueprint dynamical imaging with custom light-matter interactions will unlock access to novel deep-learning strategies towards biological sample histology.
