摘要

提出了一种基于光纤瞬变的生物传感器，通过测定胃胃肠道非恶性组织的类似折射率值来检测和识别胃肠道非恶性组织。在理论计算中考虑了当前实验数据对近红外区域肠道组织复杂折射率的一定变化。本文介绍了硫族玻璃纤维的强度检测方法。此外，根据其灵敏度和设计参数(传感区域长度和光纤芯径)在不同工作波长下的近红外区域的成就进行了近似。所设计的传感器有可能对胃肠道组织的检测产生更高的灵敏度。

Evanescent Wave Fiber Optic Biosensor: A Theoretical Study for Detection of Human Intestine Tissues

Fiber optic evanescent based biosensor is suggested for detection and identification of non-malignant tissues of gastrointestinal tract of stomach by determining their analogous refractive indices values. Current experimental data are considered for theoretical computations with certain variations of complex index of refraction of intestinal tissues in near infrared (NIR) region. Here we are describing intensity interrogation approach with chalcogenide glass fibers. Also, achievement of proposed sensor is approximated in terms of its sensitivity and design parameters (length of sensing area and core diameter of fiber) at various operating wavelengths falling in NIR region. The designed sensor has possibilities to produce higher sensitivity for detecting tissues of gastrointestinal tract.
