Abstract
We present three-dimensional, high-contrast maps of 180° domains hidden inside photorefractive crystals of BaTiO3. Some domains are columns that run the entire length of the crystal, whereas others are short needles that begin predominantly on the −c surface but disappear inside the crystal bulk.Keywords
