A method is disclosed for measuring the crystallographic orientation of a component cast by a directional solidification process. The method comprises the steps of: illuminating at least a region of the component surface with substantially coherent light, measuring the mean angle and intensity of the light reflected from the component surface, and correlating said mean angle and intensity to the crystallographic orientation of the component. The method has been found to lend itself particularly well to automation.
