K.I. Laws proposed a texture analysis method called "Texture energy measure", yieldina good classification results. We show that this method maybe implemented optically using birefringent crystals and polarisers. This optical processor can replace the computer for the major part of the computation required in texture processing. The ontical version is particularly attractive due to its reasonable cost and its high efficiency that may be estimated in the neighbourhood of 1 G operations per second using presently available components. We present some results that show the feasability of the setup.
