When a wave field is measured within a propagative medium, it is widely accepted that the resulting image resolution depends on the measuring point density, and no longer on the wavelength. Indeed, in-situ measurements allow the near-field details needed for super-resolution to be retrieved. Rarely studied in elastography, this is supported here by experiments in ultrasounds and optics. A passive elastography imaging of two inclusions in a tissue mimicking phantom is shown with a resolution down to 1/45th of a shear wavelength.
