    摘要: A composite interferometer and electro-optical prism provide a means to control the position of a spot of light to read and write data on an optical disc. In this invention each light ray from a spectral source of a cone of light rays is regenerated into a plurality of light rays by an interferometer. These rays are transmitted through an electro-optic crystal and focused by a lens into a constructive interference fringe on an optical disc. A voltage across the electro-optical crystal and magnetic field inside the spectral source define the position of the constructive interference fringe on the disc.
