The Audio Control of Laser Displays

The Present and the Future

Like other audio–frequency applications, our VIDEO/LASER projects became increasingly more involved with digital technology, microprocessors, and hybrid devices. Examples of these techniques are found in the “3–D Laser Display processor” built for VIDEO/LASER III in the spring of 1981. This equipment processes three or more input signals, and via rotation techniques and other clues, imparts to two–dimensional x–y displays the illusion of an existence in three dimensions. As digitally–based technology becomes more widespread, it is almost certain to become even more miniaturized, less software–oriented, more user–oriented, and it should therefore offer improved prospects for truly interactive performance conditions in the arts. Paralleling these developments, the future of laser technology accessible to audiences may include holographic movies and 3–D color television generated by lasers on a large scale. Beyond this, most attempts at prophecy become mere speculation. But there is an excellent chance that yet another unimagined “breakthrough” technology will emerge in the very near future, to the delight and surprise of scientists, artists, and the public, just as laser technology has emerged to surprise and delight us within the very recent past.
