Adept development requires, however, dedicated attention to the breadth of the disciplines that may be integrated into these typically diverse systems. As is surely recognized, many of the classic parallel systems have evolved to either hybrid serial/ parallel or fully serial utilizing various forms of spatial scanning to gain the operational advantages in data manipulation and transfer. It is because of this fundamental flexibility that optical scanning has engendered such a commanding role for information transfer. This temporal factor is of basic interest, for it allows (via the optical/electrical transducer-modulator and detector), efficient electronic processing. The serial form is dominated currently by familiar fields such as television, E-mail, and the reproduction of the graphic arts and sounds, utilizing an arranged timed series of pixels, pels, or voxels. The parallel form is represented classically by fields such as telescopy, microscopy, and photography-effectively rendering simultaneous transport of the information. The two principal forms of optical information transfer are identified as serial and parallel. This is a form of serial information transfer. What were the first optical scanning innovations? Semaphores? Or, how about, smoke signals? That is, amplitude modulation of scattered light from controlled groups of particulate aerosol, which disperse as they rise, as observed from a distance. Then, what is information? Consider that it means simply organized knowledge. Optical scanning is a systematic articulation of light to provide information transfer. What is Optical scanning? Let me offer a definition.
