| Abstract: | Based on curvilinear trajectory equations,the geometrical aberrations and their coefficients with second order approximation have been discussed,and the computational form also given in the paper.On the computational base of large numbers of tube type,the paper has offered the computational results of geometrical aberrations and their coefficients by two practical tubes,and given the trend of difference between geometrical aberrations with first order and ones with second order,which have certain meanings to the design and computation of practical imaging tubes. |
