Abstract
A method and apparatus for facilitating communication among circuit components mounted on a board, in which the components transmit radiation to a 'lambertian' (optically rough) surface located in opposition thereto for detection by the other components. If component identification information is included with each transmission, the present invention allows establishment of dynamically changing interconnections among any of the components on a board. The invention requires a relatively small spatial volume for implementation, and affords large data-transfer rates and freedom from electrical or other interactions.
