摘要
提出了一种采用光纤编码阵列 (OFCA)和声光偏转器实现电光 A / D转换的新方案。分析讨论了方案中的偏转器入射光发散角、衍射光斑尺寸、A / D转换位数、OFCA的窜扰。介绍了这种新的 A / D转换 (7位 ,数字输出为 842 1码 )
A new type of electro-optic analog-to-digital conversion is presented. It is based on the Optical-Fiber-Coded-Array(OFCA) and the Acousto-optic-deflector(AOD). The radiational angle of the light into the AOD, the size of diffract light, conversion bit, and the disturber of OFCA are analyzed. The experiment and result of the 7-bit A/D conversion(digital output type:8421 coder) are presented.
