Abstract
A compact instrument enables placement of the instrument such that the image of the laser beam, as retro reflected and diffracted, forms outside the tracking field of view. The target source and beam camera can be located at the focus of a Cassegrain objective. Embodiments include shared objective and twin objective design. With a shared objective design, both the beam projector and profiling camera can see the same focal length. A two objective design can use two different focal lengths.
