Abstract
A method of scanning and mapping the outer contour of a three-dimensional object, for example a person's foot, by locating a plurality of radiant-energy sensors in a circular array around the object, rotating a transmitter about the object to transmit radiant energy to the sensors of the circular array except those shadowed by the object, and utilizing detected changes in state of the sensors, and the instantaneous positions of the transmitter when a change in state is detected, for mapping the outer contour of the object.
