【 摘 要 】

The light transmission characteristics in apple tissue were studied by using laser scattering imaging and Monte Carlo (MC) simulation methods. The optical parameters of apple tissue were analyzed by laser scattering visual inspection system, and the scattering coefficient and absorption coefficient were obtained by least-square fitting method. MC method was used to simulate the light transmission of intact apple tissue. The results of MC simulation and laser scattering imaging experiments showed that the maximum error of diffuse reflectance at different locations did not exceed 3%. The internal quality of fruit is closely related to the absorption coefficient and scattering coefficient of light. The studying of the apple issue light transmission characteristics and MC simulation can help design the more effective and nondestructive detection system for fruit internal quality.
