Abstract :
A high-speed image scnnner using acoustic surface waves with tapped electrodes connected to the Si photodiode array is proposed. Reading of optical numerical characters was demonstrated with 7 bit at a scanning rate of 1 MHz. High speed of up to several tens of megahertz is promising by properly selecting the shape of electrodes and photodiodes.
