Abstract (English): this study presents a method to recover the response function of a flexible latex membrane undergoing a dynamic event by volume oscillation using Double Digital Fringe Projection to measure the profile of the surface in a sequence of frames. By applying a frequency filter to the interference pattern, a moiré pattern was obtained. Optical phase retrieval from individual frames was performed using the Isotropic Quadrature Transform Algorithm. This fringe projection technique enables full-field measurements, including edges where other techniques could not perform due to shadows generated by the tilt angle. The procedure was devised as a non-contact system to retrieve the deformation function of a flexible surface, enhancing a valuable aspect of the methodology. The results demonstrate successful recovery of the membrane response function, highlighting the relevance of the method for accurate deformation measurements using a straightforward system. These outcomes provide significant value for the development of precise measurement techniques for flexible structures in engineering applications, such as soft robotics, biomedical devices, and material science.

Abstract (Spanish): este estudio presenta un método para recuperar la función de respuesta de una membrana de látex flexible sometida a un evento dinámico por oscilación de volumen utilizando Proyección de Franjas Digital Doble para medir el perfil de la superficie en una secuencia de fotogramas. Aplicando un filtro de frecuencia al patrón de interferencia, se obtuvo un patrón muaré. La recuperación de fase óptica de cuadros individuales se realizó utilizando el algoritmo de transformación de cuadratura isotrópica. Esta técnica de proyección de franjas permite realizar mediciones de campo completo, incluidos los bordes donde otras técnicas no podrían realizarse debido a las sombras generadas por el ángulo de inclinación. El procedimiento se ideó como un sistema sin contacto para recuperar la función de deformación de una superficie flexible, mejorando un aspecto valioso de la metodología. Los resultados demuestran una recuperación exitosa de la función de respuesta de la membrana, destacando la relevancia del método para mediciones precisas de la deformación utilizando un sistema sencillo. Estos resultados aportan un valor significativo para el desarrollo de técnicas de medición precisas para estructuras flexibles en aplicaciones de ingeniería, como robótica blanda, dispositivos biomédicos y ciencia de materiales.
