Spectral properties of light migration in apple fruit tissue

The present paper simulates laser wavelength 632and 750nm Gaussian beam migration in apple fruit tissue using Monte-Carlo method,and researches the spectral properties of absorption and scattering.It was shown that the special energy distribution characteristics of Gaussian beam influenced the diffusion of the laser in the tissue,the reflection,absorption and transmittance of 750nm by tissue are lower,there are more photons interacting with tissue within the tissue,and they can more clearly reflect the information within the tissue.So,the transmission characteristics of the infrared light were relatively strong in biology tissue,which was convenient for researching biology tissue.
