N2 - In present paper, some inverse designs of realizing different focusing fields for electrostatic and magnetic imaging without image rotation but with variable magnification are investigated, some methods of optimization have been developed, a universal package of program using FORTRAN language has been drawn up, an experimental prototype of electrostatic and magnetic image intensifier with unsaturated iron medium has been designed, which can produce an image without image rotation but with variable magnification from 0.3 to 3.6.
