摘要:
A fully integrated electro-optic page-scanner comprises an optically-transparent waveguide made from an electro-optic polymer, and a linear array of electrically-addressable, spaced, parallel electrodes for selectively altering the refractive index across pixel-sized portions of the polymeric waveguide. Parallel addressing of the electrodes in accordance with the intensity pattern of a line of pixels to be recorded acts to modulate the phase front of an optical wave propagating within the waveguide in accordance with such line intensity pattern. Schlieren optics, also integrated with the page-scanner, convert the phase-front-modulated wave to an intensity-modulated pixel pattern which can be imaged onto a moving photosensitive recording element to record a two-dimensional (page) of image information. By using an electro-optic polymer as the waveguide, certain disadvantages of prior art scanning devices are eliminated.
