利用回波模拟对激光测距精度检验系统的设计
|
摘要
为解决激光测距在实际测量中受外部因素而导致结果不准确的问题,设计了一种回波模拟系统对实测结果进行检验。测距系统向回波系统发射一束窄脉宽激光,PIN(Positive Input Negative)对激光采集和光电转换,将转换完成的电信号发送至FPGA(Field-Programmable Gate Array)中,FPGA通过内置PLL(Phase Locked Loop)对电信号进行15倍频操作和高精度延时。激光驱动部分利用MOSFET(Metal-Oxide-Semiconductor Field-Effect Transistor)管开关性质产生窄脉冲信号,对激光器进行调制模拟实际测量中的回波激光,最后在测距系统中得出模拟结果。通过对同一距离和不同距离的多次测量结果表明,系统稳定性较高,精度达到0.17 m,误差为0.03 m。
In order to solve the inaccurate result of the external factors in the actual measurement of laser ranging,a kind of echo simulation system is designed to test the measured results.The ranging system emits a narrow pulse width laser to the echo system,the PIN(Positive Input Negative) pairs perform laser acquisition and the photoelectric conversion,and the electrical signal is sent to the FPGA(Field-Programmable Gate Array).The FPGA carries on the 15 times frequency operation through the built-in PLL(Phase Locked Loop)and carries on the high precision time delay.The laser actuation part utilizes the MOSFET(Metal-OxideSemiconductor Field-Effect Transistor) tube switch nature to produce the narrow pulse signal and the laser modulation simulation actual measurement the Echo laser.Finally,the simulation result is obtained in the ranging system.The results show that the stability of the system is high by measuring the same distance multiple times and different distances.Precision can be achieved 0.17 m and error is 0.03 m.
