摘要
应用检相原理,可以提取有限长度调制信号和包络解调。通过改变A/D转换器的位数,提高检相分辨率,它与检测对象的运动速度无关。这为提高检相分辨率展示了新的途径。
According to the phase-detecting principle, a limited length of modulating signal and the including divide-modulation of modulating signal may be obtained. Phase-detecting resolution can be improved by raising digits of A/D converter and is independent of the speed of detected object. This opens a new way to improving phase-detecting resolution.
