Abstract
An optical sharp fibrous needle probe includes an optical fiber in a hollow needle ending in a cutting point. The optical fiber is inserted and bonded in the hollow of the needle and then polished to take on the exact needle cutting shape. The material to be explored is pricked by the needle. A light injection and recovery device is placed at the inlet of the fiber. The material located at the sharp end of the needle backscatters the incident light and generates an endogenous fluorescence signal. A part of this luminous flux is recovered by the point of the needle and sent back to the injection and recovery device. The same analyses the light in strength, duration and wavelength and enables a diagnostics without taking the in-depth explored material. An optical telemeter placed on the outer tip of the needle enables the depth of the explored area to be known.
