| titleOfInvention | Electric field imaging method |
| abstract | Proposed is an electric field imaging method for detecting, from a two-dimensional distribution of a high-frequency electric field emanating from a high frequency circuit to be visually observed, the distribution in the immediate vicinity of the circuit. To minimize or prevent obstruction by a surface-mounted part or disturbance to the object to be visually observed, an electric field sensor is placed at a predetermined distance from a surface of the object to be visually observed, and a two-dimensional distribution of a high-frequency electric field is detected. Considering that the measured electric field distribution is due to an electrostatic field from the electric field distribution at the surface of the visually observed object, the electric field distribution at the surface is back-calculated from Gauss' flux theorem or the like, and the obtained electric field distribution is displayed or outputted. Thus, the electric field distribution at a position closer to the surface of the visually observed object is imaged while obstruction by a surface-mounted part or disturbance to the visually observed object is supressed. In addition, in the above back-calculation, the visually observed electric field distribution is multiplied by a first window function for noise reduction, resolved into a spatial frequency spectrum with a Fourier transform, multiplied by a second window function for spatial frequency filtering, and subjected to inverse Fourier transform so that predetermined spatial frequency filtering is carried out. |
