本文运用琼斯矩阵分析了相位延迟对磁光盘读出特性的影响。分析表明 ,相位延迟导致磁光盘读出信号下降 ;采用复合补偿法可克服相位延迟 ,提高磁光有效信号读出。
In this paper, Jones matrix is used to analyze the effect of phase delay on the readout characteristics of a magneto-optical disk. The analysis shows that the phase delay leads to the decrease of read signal of the magneto-optical disc. The composite compensation method can overcome the phase delay and improve the readout of the effective magneto-optical signal.
