Abstract

Una sonda optoacústica portátil incluye un arreglo de transductor de ultrasonido Y fibras ópticas con un primer extremo formado en un manojo de fibras que proporciona una entrada y un segundo extremo distal que proporciona una salida. Una guía de barra de luz retiene el extremo distal de las fibras ópticas en el mismo plano. Una o más ventanas ópticas pueden estar asociadas con, y separadas de la guía de barra de luz para prevenir el contacto entre un agente de acoplamiento y los extremos distales de las fibras ópticas, mitigando así un efecto acústico potencial del agente de acoplamiento en respuesta a la luz que se emite desde las fibras. Se puede proporcionar una lente acústica de hule de silicio dopado con TiO2, con un metal reflejante que rodea la superficie externa de la lente acústica. Una concha de sonda portátil aloja la guía de barra de luz, el arreglo de transductor de ultrasonido y la lente acústica.
