信息就是消息,就是事物的存在和变化的情况.从信息论的观点看来,无论是电学、光学及声学系统,都是用来传递信息的.电学系统传递的是随时间变化的电讯号,而光学系统传递的是随空间变化的图象.我们把有关图象的传递理论与应用技术称为信息光学.信息光学是光学最先开拓的领域之一,它可以追溯到原始光学初期.但获得迅速发展还是最近三十多年的事.50年代中期,无线电通讯理论和技术引进到光学中来,推动了信息光学的发展.此后不久,光信息理论和技术成功地应
Information is the message, that is, the existence and change of things.From information theory point of view, whether it is electrical, optical and acoustic systems, are used to convey information.Electrical system is delivered over time signals, and Optical systems transmit images that vary with space. We refer to the theory and application of image-related information as information optics, one of the first fields of optics that dates back to the early days of optics, Rapid development is still the last thirty years of the matter .In the mid-50s, the introduction of radio communication theory and technology to the optical to promote the development of information optics.From then on, optical information theory and technology should be successful
