    摘要: A fully integrated electro-optic page-scanner comprises an optically-transparent waveguide made from an electro-optic polymer formed as a Langmuir-Blodgett film, 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 formed as a Langmuir-Blodgett film as the waveguide, certain disadvantages of prior art scanning devices are eliminated.

    摘要: A fully integrated electro-optic page-scanner comprises an optically transparent waveguide made from an electro-optic polymer, and an electrode structure including a linear array of electrically-addressable, spaced, parallel electrodes for selectively altering the refractive index across pixel-sized portions of the polymeric waveguide. According to the invention, the addressable electrodes are disposed on a photoconductive substrate which facilitates poling of the polymer waveguide to rander it electro-optic in nature. During the poling process, the photoconductive substrate is made electrically conductive by flood illumination, while a uniform electric field is established between the substrate and a transparent electrode which overlies the waveguide layer, opposite the addressable electrodes. Preferably, the photoconductive substrate comprises undoped silicon which enables certain electrode-addressing circuitry to be integrated within the scanner structure.
