摘　　要：本文提出了间接耦合这个新概念,在此基础上找到了间接耦合的具体形式——注入光敏器件.文中对耦合系数进行了详细讨论.实验证实,注入光敏器件的信噪比高于普通光敏器件约两个数量级,显示出它的实用可能性.In this paper,we advanced a new conception called indirect coupling, and found the injection photsensor. The coupling coefficient is to be discussed in detail.The experimental reults indicated that the SNR (signal -to-noise ratio) of the injection photosensor is about two orders of magnitude larger than that of the ordinary photosensor.It shows that the injection photosensor has many practical uses.
