ELECTRO-OPTICAL WOBULATOR

摘要

An electro-optical wobulator includes an electro- or magneto- optically active thin film (20), disposed in an image projection path (28), and means (24) for selectively applying an electric or magnetic field to the thin film. The thin film (20) has an index of refraction that changes in response to the electric or magnetic field, thereby selectively shifting the projection path of the image.
