A family of analog CMOS velocity sensors is described which measures the velocity of a moving edge by computing its time of travel between adjacent pixels. These sensors are compact, largely invariant to illumination over a wide range, sensitive to edges with very low contrast, and responsive to several orders of magnitude of velocity. Two successful one-dimensional velocity sensors are described in detail; preliminary data on a new two-dimensional velocity sensor is shown. Work in progress to extend these sensors to processing of two-dimensional optical flow is outlined.
