| 摘 要： | 本文研究了相位式激光测距中信号干扰的机理.通过分析,本文给出了干扰信号误差的具体表现形式.采用两点标定法,确定了误差参数,利用软件对误差进行计算补偿,消除了仅依靠提高硬件性能而不能消除的干扰误差,同时论证了此法的可行性和可靠性.通过模拟仿真证明,可以极大地消除干扰误差,提高测量的精度.

| Abstract: | Mechanism of signal-jamming was studied in distance measurement with laser. The expressing of jamming sig- nal error was given through analyzing. The method of two point calibration was used to determinate the error parameter. The errors were computed and compensated by software. And the measurement error was removed which wasn't solved by hardware. At the same time,the feasibility and reliability of the method was demonstrated. The error is removed greatly,the measurement precision is enhanced,and they are proved by simulating and emulating. |
