摘要： An arrangement for deflecting a beam of monochromatic light in a rapid and accurate manner. To deflect the beam, segments of a number of Fresnel lenses are produced onto a single flat glass substrate disk. The optical axis of each of the lens segments corresponds to the center of rotation of the disk. The disk is mounted on a shaft which is rotatable about that optical axis. The beam of light to be deflected is applied to the surface of the disk at a point off the axis. When the beam passes through the disk it becomes deflected by one of the lens elements. The degree of deflection depends on the nature of the element, and the rate at which the beam is deflected from one orientation to another is determined by the rate of rotation of the disk.
