摘　　要：针对多层光盘的特点,对多层光盘的调焦系统采用了斜入射方案,保证了各层信号分离和信号强度的要求,并利用MATLAB仿真了调焦结果,搭建了相关光路,通过采集调焦信号验证了仿真结果,而且可以发现,信号强度完全可以满足采集要求。The focus system of a multi-layer compact disk are designed in order to separate the signals among dif-ferent layers and obtain the signal from the receiver and some optical instruments are used to establish the sys-tem.The focus adjustment result is simulated by MATLAB and proved by the experiments on focus system thatthe signal of each layer is received and separated by the receiver.

关 键 词：波导多层光盘 调焦系统 斜入射
