【摘要】 文中提出了一种具有自动增益控制的自触发脉冲测距方案,不但减小脉冲信号上升沿引起的测距误差,而且也减小由于信号幅度变化带来的漂移误差影响。实验结果表明:该激光脉冲测距系统在1m~10m的测距范围内,测距精度达到亚毫米级。更多还原

【Abstract】 The stable and effective detection and the increased ability of anti-jamming are the main problems to be solved in the laser range finding. In this paper the self-triggering pulsed laser range finding technology with automatic gain control is proposed. It can not only deduce the measurement tolerance caused by signal rising edge, but also reduce the walk error brought by the variable signal amplitude. The corresponding measurement results show that submillimeter resolution is obtained over 10m range.更多还原
