Abstract:
A guidance system includes a first laser device coupled to a mount, the first laser device adapted to generate a first laser signal having a first wavelength. A second laser device is also coupled to the mount and directed substantially parallel with the first laser device. The second laser device is adapted to generate a second laser signal having a second wavelength. A first photodiode is adapted to detect the first laser signal, retro-reflected from a first wavelength matched section of a reflector system, and the second laser, signal retro-reflected from a second wavelength matched section of the reflector system. The first photodiode is adapted to generate a first photodiode signal therefrom.
