Abstract
Optical image scanning utilizing the phase modulation of a surface acoustic wave in a separated medium configuration of silicon on lithium niobate has been experimentally demonstrated with two similar techniques. In on e technique the long‐lived silicon surface states are charged and the image is scanned by a short counterpropagating acoustic pulse. In the second technique the surface states are charged by a short acoustic pulse but the image is scanned by a short pulse of uniform optical illumination.Keywords
