Abstract
An optical system includes an illumination source. A lens is optically coupled to the illumination source for projecting a line image. The lens conforms to a curved profile, and the lens is a Fresnel lens. A method of projecting a line image includes generating illumination from an illumination source. The method includes focusing the illumination through a lens to form a line image, wherein the lens is as described above.
