Abstract

In terms of optical properties, most of the foods are turbid. The ability of light to penetrate a turbid material mainly depends on its absorption and scattering properties. Understanding the absorption and scattering properties of food is not only helpful to understand their chemical and physical properties, but also useful to optimize and develop effective devices for quality determination of food. To provide information for further studies on absorption and scattering properties of turbid food, the measurement techniques, such as integrating sphere, spatially resolved, frequency-domain, and time-resolved spectroscopes, and calculation algorithms, such as inverse adding double, Monte Carlo, and diffuse approximation, on obtaining absorption and scattering properties over the visible and near-infrared wavelength range were reviewed. The characteristics of these methods as well as the future trend on studying absorption and scattering properties of turbid food were also presented.

Vis / NIR范围内浑浊食品吸收和散射特性的测量和计算方法

摘要

就光学特性而言，大多数食品都是混浊的。光穿透浑浊材料的能力主要取决于其吸收和散射特性。了解食物的吸收和散射特性不仅有助于了解它们的化学和物理特性，而且有助于优化和开发用于确定食物质量的有效设备。为了提供有关混浊食品吸收和散射特性的进一步研究的信息，测量技术（例如积分球，空间分辨，频域和时间分辨光谱仪）和计算算法（例如反加双精度，蒙特卡洛，在获得可见光和近红外波长范围内的吸收和散射特性方面，对扩散和近似进行了综述。
