title: Application of moiré topography to mantle treatment.
abstract: We believe moiré topography is a particularly suitable technique for establishing contours on patients receiving mantle treatment. We derive the fundamental moiré equation from a novel, but simple, consideration of moiré phenomena. Our apparatus is designed to give a difference in height of approximately 1.0 cm between successive moiré fringes. Using an inclined plane test object, an accuracy of better than 3 mm is obtained.
