Abstract
A means of modulating a light beam with a flat response which greatly exceeds the audio range is described utilizing the linear electrooptic effect in P-type** crystals. The unit uses parallel polarized light and although it requires relatively high voltages, it draws essentially no current and has no moving parts. From the basic aspects it seems very promising for an efficient yet sturdy variable-density recording system.
