摘要：

An experimental arrangement is described for observing the images of crystal plates in diffracted light. Diffraction occurs due to changes of the optical properties of the crystal induced by striations. The colour observed for a certain region of the crystal is a sensitive measure of the dominant striation spacing. Examples demonstrate effects due to power-line fluctuations, stationary growth, cores, and interface instabilities.
