O PTICAL PATH L ENGTH AND S YSTEM G EOMETRY Optical Path Length (OPL) is the distance that light travels through an optical system. As will be discussed the geometry can be used as a microscope if the input image or target is positioned correctly. Using smooth parabolic reflectors eliminates the issues of diffraction. The input data can be parallel optical channels such as lasers or can be input images. This paper describes a different and better process of achieving the spatial to time transformation by using confocal parabolic reflectors. A significant drawback of the previous paper is that the approach has issues with construction in that the geometry described will have diffraction limited problems. Images or inputs can be manipulated and distributed using simple lenses. All of these systems including the one presented here use the parallel processing capabilities that light offers. In this case OTIS performs networking of information as described in that patent. Yet another approach called OTIS distributes data over a series of nodes optically. That paper references other processes such as CCDs, Walsh Hadamard Transforms, and Fourier transforms that can accomplish similar tasks. The positional information is converted into timed pulse position by changing the Optical Path Length of each input position relative to each other. I NTRODUCTION PREVIOUS paper describes in detail a transformation that can convert a two dimensional input into a serial string of pulses. Index Terms- Parallel processing, optical computing, image processing. This paper defines how to establish the channels and the calculations required to achieve the desired transformation. The 2D data can be images or individual sources but the light must be parallel. The transformation is achieved by changing the optical path length associated with each pixel and its channel to the output detector. Individual channels are established between the input array and the final output detector, which reads the data as a time based serial data. The optical input data are set up as a 2D array. ![]() 1, JANUARY 2014Ī Two Dimensional Optical Input to One Dimensional Serial Pulse Transformation Using Confocal Reflectors George Hulse, Member, IEEE Abstract- An optical approach using confocal parabolic reflectors is used to transform 2D input data based on spatial position to a 1D sequenced serial string.
