Optical digital pattern recognizing apparatus and method

A determination is made as to whether sequential binary bits modulating optical energy have a certain bit pattern by applying the energy to an optical line having plural points from which optical energy is derived. The propagation speed of the optical energy in the line, the duration of the bits and...
