Abstract

In this paper, we present a new micro fiber optic probe for in-vivo diffuse reflectance measurements of human epithelial tissues. The probe consists of seven, 120 x 120 microm collection fibers and one 200 microm incidence source fiber, arranged into a side-viewing configuration by using curved air-core waveguides with high optical transmittance. The outer dimension of the probe is 2 x 8mm(2). The extremely small size, high transmission efficiency and side-viewing capability of the new probe make it suitable for endoscopic spectroscopic applications inside the human body.

摘要

在本文中，我们展示了一种新型微光纤探头，用于对人体上皮组织进行体内漫反射测量。该探头由七根120×120微米的收集光纤和一根200微米的入射源光纤组成，通过使用具有高光学透过率的弯曲空气芯波导排列成侧视配置。探头的外部尺寸为2×8毫米（2）。这种新型探头极小的尺寸、高传输效率和侧视能力使其适用于人体内部的内窥光谱应用。
