Abstract
Systems and methods for use in carrying out rail track corrections. A projector device is positioned on a vehicle deployed ahead of a rail maintenance vehicle and includes a Fresnel lens and a plurality of light emitting diodes arranged to provide a light beam that provides a uniform 'spot.' The projector device modulates the light beam in such a manner that a pair of receiver receivers disposed on the rail maintenance vehicle can detect the light source and the light intensity and frequency of wavelength of light received into each receiver of a receiver pair is substantially equal. Recorded values may be used to triangulate the geometry of the section of track being worked, while a computer compares the previous section of track already corrected to the current section and makes calculations for desired corrections to be made at work heads on the rail maintenance vehicle.
