摘要:

A ferroelectric triglycine sulfate crystal was illuminated by an intense CW laser beam; light scattered by the crystal at right angles to the beam was observed visually and photographed. The visible scattering column was found to be crossed by a series of bright lines oriented parallel to the ferroelectric axis whose appearance under various electric field and temperature conditions strongly suggest that they correspond to boundaries of ferroelectric domains. It therefore appears that this technique will permit direct observation of domain dynamics which, in the past, has been possible only with indirect techniques.
