Abstract

X-rays and visible ray can be simultaneously incident upon the same range of an object to be radiated by making an axis of X-rays radiated be identical or almost identical with an axis of visible ray reflected. X-rays can be accurately radiated on the point, on which visible ray was projected, without secular change even though the surface of said object to be radiated, on which X-rays are radiated, is rough.
