Abstract
An interferometer is used to provide control to the intensity profile and position of a spot of light. In this invention, each light ray from a spectral source is regenerated into a plurality of light rays by an interferometer. These rays are focused by a lens into a constructive interference fringe on a focal plane. A voltage across the interferometer can change the index of reflection of the interferometer thus defines the position of the constructive interference fringe on the disk.
