Abstract In the previous stage we had developed the water tube tiltmeter based on CCD. Through the test we found that its antiinterference 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.
Key words :
CCD
water tube tiltmeter
difference structure
pulse delay
circuit subdivision
