目的：研究光在苹果组织中的散射光强分布特点。方法本文采用激光与机器视觉技术，分析自然苹果(具有果皮果肉双层组织)，削皮苹果(仅具有果肉组织并保留天然形状)，长方体果肉这三种样本中的散射光强分布。结果苹果组织内部光场是一个球形分布；苹果竖切面形成的散射光强分布图在横向和纵向上的光强分布为高斯分布，等亮度线为圆形分布；苹果皮对光有部分吸收，使得光在单层组织中比双层组织扩散范围大；在相同径向距离处，苹果弧度的变化引起等亮度线的向外移动。结论苹果内部散射光场的大小及光强分布受苹果果形、果皮的影响，实验结果从光学角度为利用激光图像法来实现水果内部品质的无损检测提供参考。

Objective To study the distribution characteristics of scattered light in apple tissue. Methods The technology of laser and computer vision were used to analyze the scattering intensity distri-bution of the natural state, the peeled, the cuboid apple from the optical point. Results Apple internal light field was a spherical distribution. Light spot image formed apple section in the horizontal and vertical dis-tribution of light intensity was similar to the Gauss distribution, and brightness contour approximated to two multinomial distribution. The apple peel had the absorption effect on light, so that the range in monolayer tissue was bigger than that of the double organization diffusion. In the same radial distance, brightness con-tour outward shift caused by the changes of apple radian. Conclusion The size and intensity distribution of scattering light field in apple tissue were affected by fruit shape and peel. The experimental results from the optical point for the use of laser image method provided reference to realize the nondestructive detection of fruit internal quality.
