Optical fibre sensor for detection of atherosclerotic lesions

摘要

This paper presents the design of the side-polished optical fibre sensor. The polished core on one side of the optical fibre excites the fluorescence phenomenon inside the tubes by emitting rays of light outside the optical fibre cor. The sensor constructed in this way can be used both in industry and in the medicine. This article discusses the ability to collect information about the condition of blood vessels in the human body, which is the intended practical use of the sensor. An important part of the design process is the selection of a suitable optical fibre, the bend radius and the length of the polished fibre fragment so as to obtain optimal power concentration in the investigated place. The entire process taking place in the optical fibre was simulated using the Ray tracing method with optimised fibre optic parameters.
