| 摘 要： | 为了适应当前的自适应光学系统的要求，介绍一种多路D/A转换电路的优化及实现方法。它将输出的多路数字信号依次地通过一路D/A，进行数模转换，再通过采样保持器，将各路信号进行采样保持，分成了多路信号来控制变形镜，从而不但简化了系统，而且综合小信号误差，减少故障率。

| Abstract: | In order to meet the present requirements of adaptive optical system, an optimization and im- plementation scheme for multi-channel D/A converter circuit is presented. The output multiplexed digital signals will pass through a group of D/A converter one after another, thus the D/A conversion can be carried out. Then the signals from various channels can be sampled and hold through sampling holder, and distributed to control deformable mirror. This arrangement not only simplifies the system constitution, but also decreases the signal error and fault rate. |
