Feasibility Study on Measuring Composition Concentration in Turbid Media by Response Variable Transform Method

研究了基于响应量转换法测量浑浊介质中成分浓度方法的可行性,以Intralipid为研究对象,通过(monte carlo,MC)结合反向倍增法(inverse adding doubling,IAD)算法的模拟实验和双积分球系统结合IAD算法实验的方法,验证了IAD算法和双积分球系统提取散射信息的有效性,并进一步考察了散射系数预测成分浓度的可行性。结果表明,基于响应量转换法测量浑浊介质中成分的浓度有效可行,用散射系数与浓度的线性关系模型预测浓度的相对误差保持在10%以内。

The present paper primarily studied the feasibility of the measurement of composition concentration in turbid media using response variable transform（RVT） method.With intralipid as the subject,the simulation of Monte Carlo in conjunction with the IAD algorithm and the experiment of double-integrating-sphere system combined with the IAD algorithm were conducted to verify the effectiveness to extract the scattering information.Furthermore,for the feasibility of the scattering coefficient to predict the concentration of intralipid,the results showed that measuring the component concentration in turbid media by means of RVT method is effective and feasible,and the relative error to predict the concentration with the linear relationship between scattering coefficient and concentration of intralipid is less than 10%.
