Abstract : The use of a rotating diffusing screen is reported for obtaining domain pattern pictures of high contrast in the Kerr-effect microscope working with a helium-neon continuous wave laser. A brief review analysis is presented to examine the origin of the speckled appearance and the methods for its elimination. The present experimental technique gives completely satisfactory results and is illustrated by a few domain photographs obtained with this apparatus. (Author)
