Abstract :
A technique for image-velocity computation is described. Using one set of intersecting delay lines that are physically perpendicular to each other, the two perpendicular components of image velocity can be computed separately if the image area is known. To compute the image velocity without knowledge of the image area, two sets of intersecting delay lines are required. This technique is suitable for analog VLSI implementation
