Abstract
Optical ground tracking apparatus for use with buried object locators or other instruments or devices are disclosed. In one embodiment, a method for tracking movement of a buried utility locator over a surface includes generating an output light, providing the output light to the surface, receiving a portion of the output light that is reflected from the surface, and generating information associated with a user-applied movement of the locator over the surface based at least in part on the received reflected portion of the output light.
