Abstract
An optical navigation system for determining movement relative to a navigation terrain includes a first source and a second source of optical radiation for illuminating the navigation terrain, the first source differing from the second source in at least one operating parameter. The system further includes means to select the first source and the second source independently based on decision criteria. The system further includes a detector for capturing patterns in the optical radiation subsequent to illuminating of the navigation terrain.
