Abstract
A design that builds on well-known schemes using gratings is outlined. The key development here is the use of commutation as a means of modulating the grating output signal. This enables backwards and forwards motion to be distinguished. Results from an analog implementation of the visual motion transducer are presented. The current transducer measures translational motion across the grating. The design is also shown to be capable of extension to direct measurement of the divergence and curl of the flow field
