The atomic hologram

The experimental setup developed in Japan uses electrons to excite the emission of x-rays from titanium atoms in strontium titanate (molecular formula SrTiO3). The emitted x-ray waves interfere with the waves scattered by the surrounding atoms, thus forming a hologram of the 3D atomic arrangement in the material.
