ABSTRACT:
A balancing system for balancing an object mounted thereon in a predetermined plane. The balancing system includes a laser mechanism for producing a coherent first beam of visible electromagnetic radiation in a substantially vertical direction line. A beam splitting member inclinable with respect to the vertical direction line upon imbalance of an object mounted on the balancing system intercepts the first beam of coherent light emitted from the laser. The beam splitting member is adapted to pass the first beam of light external to the balancing system and to reflect a portion of the first beam of light into a second coherent beam of light due to reflected passage within the beam splitting member when the member is inclined with respect to the vertical direction. The first and second beams of light intercept a target area remote from the balancing system and provide a pair of displaced visible light points determining the unbalance of the object mounted on the balancing system. Upon adding weights to the object in appropriate areas, the first and second beams of light become coincident each with respect to the other, thus defining a balanced condition of the object.
