  • Patent number: 7219438
    Abstract: A temporary visible image, such as a first down reference line, corporate logo, or text is projected onto a target surface by an orientation-stabilized, fiber-fed laser projector. The projector may include at least one cylindrical lens or at least one pair of X-Y scanners. One or more remotely located lasers, supplying optical energy at a single wavelength to the projector, accommodate projection of a monochromatic line pattern. Multi-colored images are accommodated by supplying, to the projector, the output of a plurality of lasers operating at different wavelengths within the visible band. The projector is suspended and conveyed as a unitary assembly by a suspension system adapted to maintain the projectors angular orientation and dynamically stabilize the image. If desired, two or more independently-suspended projection modules or groups of modules adapted to move in unison or independently over the length of the field may be employed.
