摘要:
结合双路调频干涉的高精度优点,以四波混频技术取代其中一路调频激光器,设计了双路调频激光绝对距离测量系统。Matlab数值模拟结果显示:在不考虑四波混频等非线性效应影响的情况下,双路调频激光绝对距离测量系统的测量精度较单路调频测距系统提高了近1个数量级,可以显著降低单路调频测距系统因待测物体振动、气流扰动等因素对测距精度的影响,所设计的系统是合理有效的,并具有简便性和经济实用性的特点。
Abstract:
Dualfrequency absolute distance measurement by tunable diode lasers were designed with the characteristic high precision of dual frequency interferometry,using four wave mixing techniques in place of one tunable laser.According to matlab simulation results,this system is one order of magnitude better than the single frequency ranging system taking no account of nonlinear effect of four wave mixing.It significantly reduces the measurement error due to vibration and airflow disturbance,and is therefore effective with low complexity and low cost.
