Abstract

A new kind of camera has been devised which records depth profiles of scenes directly on photographic film. If the object surface is described by S(x, y, z), where z is the depth dimension, then a normal photograph records ∫s(x, y, z)dz The new camera might record S(xo, y, z) or S(x, yo, z) where xo and yo are easily variable parameters. Many such profiles in rapid succession provide a full 3D record of the scene. The camera uses a slit in an ordinary image plane to restrict the x or y information and laser rangefinding with a modelocked laser to obtain the z information. Depth resolution of one mm or less is achievable. Applications to whole body imaging and internal 3D photography are discussed.
