Acoustical scanning of optical images
Abstract
The parallel research efforts of high barrier height Schottky diodes and Sezawa wave storage correlators have been integrated and storage has been demonstrated with 1 ns pulses. Storage times in storage correlators of 400 seconds have been demonstrated by cooling to -75 C. The initial experiments in flaw discrimination indicate the possibility of discriminating between different size voids, and discriminating between filled and unfilled holes. Broadband (42%) active matching circuits have been implemented and a design is investigated for making active matching circuits without the use of any indicators.
