ABSTRACT:
An optical alignment system includes a transmitter of a beam of radiant energy and receiver thereof. Both the transmitter and receiver carry a plurality of light emitting diodes. As the optical alignment between the transmitter and the receiver is altered, the number of diodes which is energized is increased or decreased in response to increasing or decreasing the optical coupling therebetween.
