An optical toe/track measurement system includes a pair of toe gauge assemblies respectively mountable on the two wheels at one end of a motor vehicle and a pair of track scale assemblies respectively mountable on the other two wheels of the vehicle. Each toe gauge assembly includes an elongated tubular housing having toe and track projection systems for respectively projecting toe and track light beams from the opposite ends of the housing, the track beam being projected coaxially with the housing onto the track scale on the same side of the vehicle, while the toe beam is projected perpendicular to the longitudinal axis of the housing onto a scale carried by the toe gauge assembly on the other side of the vehicle. Light is supplied respectively to the two toe gauge assemblies throught two fiber optic cables from a single remote light source. Each fiber optic cable has an input end which plugs into a receptacle in the source enclosure and a bifurcated output end which is optically coupled to both of the projection systems in the associated toe gauge assembly.

Apparatus for measuring wheel alignment of a motor vehicle comprising: light projection means; means for mounting said light projection means on one wheel of the vehicle in a predetermined position and orientation; scale means mountable on another wheel of the vehicle; a light source remote and substantially thermally isolated from said projection means; and fiber optic means for transmitting light from said source to said projection means, said projection means being responsive to light from said fiber optic means for forming a light beam and projecting it onto said scale means.
