摘要

Disclosed is the three-dimensional scattering distribution when the scatterer is subjected to electromagnetic radiation of certain wavelength distribution, and provides a scattering property measuring device for measuring the physical properties of the scatterer. A Place the scatterers to be measured in a sample mounting table, a virtual sphere the electromagnetic waves centered on the focal point, one or more arbitrary directions, and, in the direction of consecutive one or more, at least one of irradiating the scatterer from the direction, is captured by the imaging means that when the reflected or projected scattered wave which is the parabolic mirror or a parabolic screen is scattered by the scattering body as planar imaging data thus the obtained image data, the center to give a three-dimensional distribution of scattered waves generated from the scattering body, in the case of measuring the physical properties of the scattering body from the result, the scatterer the scattered wave to image over a smaller range than the arc of 3π / 4 radians in the section including the center axis of the virtual spherical surface.
