We demonstrated the use of the analog self electro-optic effect device (SEED) as part of an artificial retina chip for the detection and estimation of local motion. The characterization was performed by comparing our chip to biological and computational models and to other artificial retina chips. Its main unique feature is the optical output, since most chips have electrical output. By combining the response of the chip with temporal information about the input image, it is possible to estimate the velocity perpendicular to an edge, including its direction.
