Abstract
A technique is described which utilities certain properties of thin liquid crystals to convert the distribution of an electromagnetic pattern into a corresponding visual display, without the need for scanning. Plates covered with a layer of cholesterol have been prepared which changed their local coloration in proportion to the intensity of microwave radiation. Some theoretical explanationss are suggested and applications mentioned.Keywords
