摘要：
A probe (10) with a scanning system (28), comprising: a plurality of optical elements (29), comprising: an optical fiber (22, 40), having a fiber axis (44) which is the optical axis of the fiber, the optical fiber being configured to transmit a ray of light (34), the fiber axis (44) extending towards an imaginary fiber axis (46) that is in the same direction as the fiber axis； and a gradient index lens (GRIN) (42) having a GRIN perimeter (50) and a GRIN lens optical axis (48), where the GRIN lens is configured to receive the light beam from the optical fiber and refract the ray of light； and a movement system (30) comprising a cylinder (33) having a cylinder axis (35), where the GRIN lens (42) is disposed off-center within the cylinder so that the cylinder axis is substantially parallel a but is separated from the optical axis (48) of the GRIN lens, characterized in that the probe comprises a cannula (26)； the plurality of optical elements (29) and the movement system (30) are disposed within the cannula (26)； and the movement system (30) is configured to rotate the cylinder (33) around the cylinder axis (35) to move the off-center GRIN lens separately from the optical fiber in a substantially circular closed path (52), of so that the GRIN lens does not rotate around the optical axis (48) of the GRIN lens, but that the optical axis of the GRIN lens is substantially aligned with the imaginary fiber axis (46) at least one point of the path, and the GRIN perimeter (50) intersects the imaginary fiber axis (46) at least two points of the path (52).Una sonda (10) con un sistema de exploración (28), que comprende: una pluralidad de elementos ópticos (29), que comprenden: una fibra óptica (22, 40), que presenta un eje de fibra (44) que es el eje óptico de la fibra, estando configurada la fibra óptica para transmitir un rayo de luz (34), extendiéndose el eje de fibra (44) hacia un eje de fibra imaginario (46) que está en la misma dirección que el eje de fibra； y una lente de
