摘要
介绍通过差分式结构设计和脉冲延迟细分方法解决CCD水管倾斜仪的抗干扰能力较弱、分辨力不高等不足。
In the previous stage we had developed the water tube tiltmeter based on CCD. Through the test we found that its anti-interference ability and resolution can not meet the requirements. This paper mainly introduces how to solve the existing problems through the design of mechanical difference structure and circuit subdivision method of pulse delay.
