Abstract
A laser based coordinate measuring device measures a position of a remote target using a camera having an adjustable magnification set based on the distance from the coordinate measuring device to the remote target. The laser based coordinate measuring device includes a structure rotatable about two axes. The device includes a distance meter, a position detector for use in tracking the remote target, and two angular encoders for measuring the angles about the two axes.
