Abstract
A calibration device which has at least two targets. Each target has at least one surface exhibiting areas of optical contrast, and each surface has a general plane of orientation. The targets are oriented such that a general plane of orientation of one target is inclined at an angle relative to the general plane of orientation of a surface of the second target which has areas of optical contrast.
