Abstract: Alignment difficulties in optical computing arrangements are overcome by integrating a number of the optical components on a single substrate and arranging the elements in a manner that causes them to interact with one another to perform the desired functions, such as image manipulations. the substrate has one or two major surfaces and the elements are fabricated on those surfaces using conventional integrated circuit manufacturing techniques. Most advantageously, the position-sensitive optical device are manufactured on one side of the substrate, obviating the need to align two masks during the manufacturing process.
