Abstract

Optical spectroscopy is becoming a very valuable diagnostic tool in biomedical research. Time-of-flight spectroscopy is a tool providing information regarding scattering and absorption properties of the tissue. A unique broadband time-resolved spectroscopy system for turbid media, consists of a mode-locked Ti:sapphire laser pumping a photonic crystal fibre (PCF) and a streak-camera in syncroscan mode. This system is based on the technique called time-correlated single photon counting (TCSPC). This equipment is designed to allow in vivo measurement of tissue optical properties of small tissue volumes.

生物医学诊断中的飞行时间激光光谱学
光谱学正在成为生物医学研究中非常有价值的诊断工具。飞行时间光谱学是一种提供有关组织散射和吸收特性信息的工具。一种独特的用于浑浊介质的宽带时间分辨光谱系统,由锁模钛蓝宝石激光泵浦光子晶体光纤(PCF)和同步模式的条纹相机组成。该系统基于时间相关单光子计数(TCSPC)技术。该设备设计用于在体内测量小组织体积的组织光学特性。
