Abstract
A digital scanner composed of a plurality of individually addressable scanning elements. Each of the plurality of individually addressable scanning elements capable of operating in discrete states in response to digital input signals applied to the digital scanner, thereby providing for either a straight passage and optical deflections or displacements, of a light beam passing therethrough dependent upon the state of operation of each scanning element. The scanner thereby capable of steering light over many positions according to digital input signals.
