Abstract
Light transmitted properties of chicken muscle tissue are experimentally measured under the condition of far field.And the results show that slice muscle tissue can make the incident laser beam generate obvious diffraction phenomena.In order to interpret the experimental results,the radiative transfer theory is modified and the diffraction effects are considered in the modified theory.According to the modified model,theoretical calculation is executed for light transmitted properties of chicken muscle tissues and the result is well matched with the experimental results.
