摘　　要：本文的目标是研究一种无损检测温度对介质特别是生物组织光学特性影响的新方法。以牛奶作为样品,将其从低温开始加热,温度跨度从20-35℃,利用光学相干层析成像仪(OCT,中心波长为850nm)每隔5℃对牛奶进行一次成像取得对应的OCT信号强度数据。经过分析发现,当温度升高时,OCT系统探测到信号的衰减系数随之增大。这是一种研究温度对生物组织光学衰减系数影响的新方法。The objective of this study was to develop a new method for monitoring the effect of temperature on the optical properties of biological tissue. Its have been studied by using milk as an example. Optical properties of milk were measured by using optical coherence Tomography （OCT,the center wavelength is 850nm） technology in the temperature range of 20-35℃, and we get the logarithm of the OCT signal, then the rules of change of optical properties with temper_ature were analyzed. The results show that obvious increase can be observed with increasing temperature in the increase attenuation coefficient. It is a novel method to study the effect of temperature on optical properties of biological tissue.
