Abstract
A method and apparatus for taking impressions of a portion of the body which utilizes the projection of a grid of sinusoidal profile onto the body portion of which the impression is to be taken. The projections are phase-shifted and resulting images are memorized and from the memorized images, the variations in intensity resulting from the phase-shift at each given point can be ascertained to enable the configuration of the region to be calculated.
