A linear lens consists of a linear array of small imaging elements. Each element images a small area of the object, and images of adjacent elements form a continuous linear image as long as the array and as wide as the image of one of the elements. Contiguous pixels in the object must be contiguous at the image whe0n imaged by different elements. Since a simple lens rotates an image 180 contiguous pixels in the object will not be contiguous when imaged by adja-ent simple lenses. In the linear direction, the image must be rotated another 180 so that the images formed by adjacent elements will form a long, continuous image.
