Abstract:
A hologram observation method for estimating a three-dimensional wave source distribution by a hologram observation, comprising the steps of:(i) performing a hologram observation at different frequencies to reconstruct a hologram image at each frequency, said reconstructed hologram image comprising a wave source image;(ii) selecting a wave source of interest as a measuring area from said wave source image;(iii) obtaining three-dimensional coordinates of the selected wave source in said area;(iv) synthesizing a hypothetically observed wave as if a virtual wave source having a unit exists at said three-dimensional coordinates and accordingly reconstructing a hologram image; and(v) obtaining an accurate wave source intensity from a ratio of a wave source intensity in the reconstructed hypothetical hologram image in step (iv) to a wave source intensity of the selected wave source in step (ii) thereby accurately estimating a three-dimensional wave source distribution.
