摘要: A method for aligning a layer of photopolymers includes projecting light onto rotating optical element and asymmetrically focusing the transmitted through photopolymers. The focused is swept across different regions while direction polarization in varied due to rotation first element, producing pattern orientations can be incorporated raster-scanning process produce an alignment with large surface area, faster provides improved precision and/or uniformity compared currently available methods. An apparatus also disclosed.
