Abstract

Abstract The paper presents the analysis of the functional abilities of measurement tools with ellipsoidal reflectors for Raman spectroscopy. The investigated structural scheme of the setup is intended for use in Raman spectroscopy in vivo by ellipsoidal reflectors. The setup can be used as a prototype for development of a device for non-invasive control of sugar level. Additionally, the investigation demonstrates the efficiency of ellipsoidal photometry method for registration of Raman scattering signal on test-solutions. The testing was performed for different sugar concentrations with the laser radiation wavelength 980 nm. In addition, the selecting principles of laser radiation source parameters (including beam diameter and power) were investigated. During the research, the data about spatial distribution of the backscattered light in human shoulder and finger tissues during photometry by ellipsoidal reflectors were received. The procedure involves application of Monte Carlo simulation. The dependency of the external and middle ring illuminance of photometric images on the diameter and power of the laser beam is represented based on the zone analysis.

椭圆反射镜体内诊断的拉曼光谱原理

摘要本文分析了具有椭球反射镜的拉曼光谱测量工具的功能。所研究的装置结构方案旨在通过椭球反射器在体内拉曼光谱中使用。该装置可作为开发无创血糖水平控制装置的原型。此外，研究证明了椭球光度法在测试溶液上配准拉曼散射信号的有效性。用980nm的激光辐射波长对不同的糖浓度进行测试。此外，还研究了激光辐射源参数（包括光束直径和功率）的选择原则。在研究过程中，接收了椭球面反射器测光过程中人体肩指组织中后向散射光的空间分布数据。该过程涉及蒙特卡罗模拟的应用。基于区域分析来表示测光图像的外环和中环照度对激光束的直径和功率的依赖性。
