A technique for optically processing time varying signals has been investigated. The electronic optical system described in this paper readily provides the power spectral density content of an input time function. The objective of this effort was to design a prototype coherent optical processing system to generate the power spectral density of electrical signals supplied directly from a sensor or stored on magnetic tape. The task encompassed a definition of functional components, investigation of important parameters, performance tests, and measurements.
一种用于光学处理时变信号的技术已得到研究。本文所述的电光系统能轻松提供输入时间函数的功率谱密度内容。这项工作的目标是设计一个相干光学处理系统原型，以生成直接来自传感器或存储在磁带上的电信号的功率谱密度。该任务包括功能组件的定义、重要参数的研究、性能测试和测量。
