Abstract
The optical twins in grains of the high temperature superconducting material, YBa2Cu3Ox, lie along {110} planes, and the long boundaries of elongated grains are basal planes. Equations are presented utilizing these facts, which allow the apparent twin spacing to be converted to true twin spacing by measurement of the angles between twin sets and the basal plane boundary on the polish surface. The true thickness of the elongated grains in their C axis direction may also be determined from the analysis.
