Abstract: The rotation angle of light polarization direction is calculated by using the change in light intensity

after the light passes through the optically active solution,thereby calculating the optical rotation rate of the solution. We analyze the influence of various factors on the results in the experiment,and give the improved method and correct the final calculation formula. The data is measured by experiments to verify the correctness of the theory.
