本文介绍了一种激光扫描检眼仪的消色散电路。该电路可补偿声光偏转器产生的色散,提高彩色图像的清晰度,增强该仪器的辅助诊断作用。
A dispersion correcting circuit of SLO is presented. The circuit can compensate achromatization produced by the acoustooptic deflector and enhance sharpness of the colour image for better diagnosis.
在用偏振度作为反馈信号的动态偏振模色散补偿系统中,偏振度与差分群延时的关系对于准确快速的动态偏振模色散补偿很重要。
It is important to know how does the degree of polarization (DOP) change with differential group delay (DGD) when DOP is feedback information for adaptive PMD compensation.
但采用偏振度椭球取样方法,其补偿的误码特性明显要优于单偏振度取样,从而补偿了高阶偏振模色散。
When the DOP ellipsoid sampling method is used the performance is evidently better, because the effect of high-order PMD on PMD compensation is reduced.
