Abstract	The flow imaging procedure of electromagnetic holographic measurement requires an adequate establishment of sensitivity field. Currently, the widely adopted Geselowitz sensitivity field for most of the electric/magnetic imaging is not applicable in the flow imaging of electromagnetic holographic measurement. In this paper, in accordance with the mathematical basis of tomography - Radon transform and its inverse transform, through a combination of the physical meaning of sensitivity field and the characteristics of electromagnetic holographic measurement approach, a holographic measurement sensitivity field is established through the gradient of electric potential. Through the numerical test by Finite Element Method, it shows that the new sensitivity field is beneficial to overcome the “soft field effect” through the validation of electromagnetic holographic measurement data, it shows that the response obtained by the new sensitivity field is in better agreement with the theoretical, thus to indicate that the holographic measurement sensitivity field established in this paper is applicable to flow imaging procedure of electromagnetic holographic measurement.
