摘要

本文就生物組織折射率的意義進(jìn)行了論述，引入一個(gè)表觀的具有平均意義的參量作為生物組織折射率用于描述光在不同組織分界面上的行為以及光在組織內(nèi)傳播的時(shí)間特性；提出了測(cè)量生物組織折射率的前提條件和幾種新的測(cè)量方法并評(píng)價(jià)了這些方法的優(yōu)劣性；接著，給出了典型組織折射率在不同環(huán)境條件下的測(cè)量結(jié)果，同時(shí)進(jìn)行了分析和討論，形成的結(jié)論可以對(duì)生物組織折射率性質(zhì)有初步的認(rèn)識(shí). 組織光學(xué)是一個(gè)光學(xué)與生命科學(xué)相互交叉相互滲透的新興研究領(lǐng)域,其根本任務(wù)是為醫(yī)用光子技術(shù)的發(fā)展提供理論基礎(chǔ)它是組織光學(xué)研究的基本內(nèi)容;同時(shí)評(píng)述了現(xiàn)有光傳輸理論,如漫射近似,Monte Carlo 模擬等的優(yōu)缺點(diǎn)及適用條件,探討了處理實(shí)際光傳輸問(wèn)題時(shí)近似理論的合理選擇問(wèn)題。

Abstract
The senses of refractive index in biotissue are discussed an apparent index of refraction, or average spacial refractive index as an additional basic optical parameter of biotissue in authors' opinion, has to be introduced to solve various boundary and temporal problems. The prerequistite conditions to measure the refractive index of biotissue are presented. After several measurement methods reviewed, themeasurement result of typical refractive index of biotissue are provided in various environment conditions. Tissue optics is a rapidly expanding field of great interest to those involved in the development of optical medical technologies. In this review , the basic problem of Tissue optics —“l(fā)ight transporting in biological tissues”is discussed and all kinds ofmethods are analyzed , which are used to deal with light transporting in biological tissues. After then, relative merits and servicecondition of all kinds of methods in existence are presented. Finally, how to select an appropriate method for practicalproblem isalso discussed. The analyses and discussions are provided from which the properties of refractive index of biotissue can be obtained.
Keywords: Biotissue ; Optical Property; Scattering; Averagerefractive index; Internal totalreflection
