Title:
HIGH SPEED ELECTRO-OPTICAL ANALOG-TO-DIGITAL OR DIGITAL-TO-ANALOG CONVERTER
Document Type and Number:
Japanese Patent JPS5744130
Kind Code:
A
Abstract:
1. A high-speed, electro-optical analogue/digital converter, having a planar phase diffraction grid, where the analogue signal is connected, as electric voltage signal, to a grid-like electrode structure, and where the intensities of the individual, deflected light rays produce the dual digits of the digital output signal, characterized in that a plurality of planar Bragg deflectors, for each of which the light intensity of the diffracted rays is perioddependent upon the connected electric voltage with a different period, for the production of an equal number of ray positions, considered from the direction of the oncoming light beam, are arranged one beside another in this beam, where the Bragg deflectors are inclined in such manner that light hits are relevant grid structure at the respective Bragg angle.
