A six-light-screen structure was presented.By the method of the analytic geometry,the equations of six light screens were built according to the geometry relation between the six light screens,and combined with the trajectory equations with unknown parameters.The times of the pill flying through the six screens in turn were fed into joint equations,and the unknown parameters of the trajectory equations were obtained.The coordinates of the intersection points of trajectory track and prearranged light screens were obtained.The measuring principle was given,and the measuring precision was analyzed.The result shows that vertical target of six-light-screen is more coincident with the real firing conditions than vertical target of four-light-screen.
