混浊介质中随机微结构的定量检测一直是光学和声学观测的难题。提出了一种光声光谱匹配的方法来解决这一问题。这种方法允许我们使用长波长定量检测随机微结构的特征尺寸。使用约375 μm的工作波长，我们精确地测量了隐藏在混浊幻影中的粒子的尺寸（49，94.8和199 μm）。由于由颗粒组成的随机微观结构通常出现在组织中，因此这种方法可能提供对生物体内深层生理和病理过程的洞察。
Quantitative detection of stochastic microstructure in turbid media remains a challenge to both optical and acoustical observation. A method of photoacoustic spectral matching is proposed to solve this problem. This method allows us to quantitatively detect the characteristic dimension of stochastic microstructures using a long wavelength. Using a working wavelength of about 375 μm, we accurately measure the dimensions (49, 94.8, and 199 μm) of particles hidden in turbid phantoms. Since stochastic microstructures composed of particles commonly appear in tissue, this method might provide an insight into the physiological and pathological processes deep within organisms.
