Synthesis of noncontact probes for charge and potential microdistribution measurement

The solution of the noncontact probe synthesis problem is suggested. Some characteristics of the system are known: the distance between the probe and the research surface, the thickness of layers, the dielectric permittivity of layers. The layers are plane-parallel. The function, which describes transformation of surface charge or potential distribution into an electric signal, is equal 0 on the boundary surface except the probe plane. On this plane the function is unknown. The expressions for determination of this function on probe surface according to the given spatial transformation coefficients for charge or potential are received. It is possible to make this function by technical or (and) program means. The experimental results are considered.
