A 3-D scanner that employs white laser light and yields high-resolution data in files small enough to be handled on a graphics desktop or readily communicated using a modem is discussed. At its heart is a synchronized sensing system that frees up the axis in the data file. The resulting independent depth of field makes it possible to adapt the scanner to a variety of industrial and scientific applications. Because the pixels registered on the CCD camera are used for z coordinates only, the camera can extract more resolution. The system also reduces distortion from shadows and ambient light.<>
