Abstract :
A PLZT thin film device has been constructed in which the photoinduced current represents the dot product between a stored image and an image projected onto its surface. One-dimensional autocorrelations have been performed by measuring this current while displacing the projected image. This device has the potential to perform as a high-resolution, high-speed optical comparator
