导出了光子在非定域光学反常包埋体中的平均时间。结果的准确性进行了测试，对Monte Carlo和实验数据。我们表明，吸收夹杂物的吸收系数的量化，需要一个校正因子，考虑到夹杂物的大小。这一发现表明，用于逆算法中使用的非常小的夹杂物的微扰方法，需要一个校正因子，以充分量化的微分吸收系数的非本地化的目标嵌入在光学混浊介质。©2002年摄影光学仪器工程师协会。
The mean time spent by photons inside a nonlocalized optically abnormal embedded inclusion has been derived analytically. The accuracy of the results has been tested against Monte Carlo and experimental data. We show that for quantification of the absorption coefficient of absorptive inclusions, a corrective factor that takes into account the size of the inclusion is needed. This finding suggests that perturbation methods derived for very small inclusions which are used in inverse algorithms require a corrective factor to adequately quantify the differential absorption coefficient of nonlocalized targets embedded in optically turbid media. ©2002 Society of Photo-Optical Instrumentation Engineers.
