Abstract
An electromagnetic field high speed imaging apparatus, using an image sensing element having a filter function for each pixel, converts a local polarization state in detection light containing a difference frequency component Δf (|fLO−fRF|) between the modulation frequency fLO of irradiated light and the frequency fRF of the electromagnetic field emitted from a subject into local intensity of light, and captures it by an image sensor of an imaging unit to generate a two-dimensional image of distribution of the near electromagnetic field emitted from the subject. Each pixel of the image sensor comprises a photoelectric conversion element for converting the detection light from the optical unit into an electric charge, a plurality of charge storages, and a charge splitting part for dividing the electric charge generated in the photoelectric conversion element between the plurality of charge storages.
