Since the wavelengthes are long in such waves, improvement of resolution is necessary, because the apertures of hologram planes are narrow compared with the optical holography, resulting in the low-quality reconstructed image.

Such a state of the scatterers’ distribution is named “extra-speckle condition”. The statistics of the interference pattern in the extra-speckle condition is investigated.
