人眼安全激光测距系统误差分析
Error analysis of eye-safe laser rangefinder
【摘要】 通过对晴朗、轻雾和白磷烟雾3种条件下激光测距机实际任务数据进行对比,分析大气扰动中质量消光系数和模糊物衰减中测距概率等参数对测距精度的影响,得出大气扰动和模糊物衰减与测距概率之间的关系公式,提出采用发射多脉冲提高探测概率和增加测距脉冲频率提高信噪比(Signal to noise ratio,SNR)的改进措施,为提高激光测距机性能提供了理论依据。
【Abstract】 Practical detection data of laser rangefinder under three weather conditions with sunny,light fog and white phosphorous smoke,were compared to analyze how the range accuracy are influenced by the parameters such as attenuation mass extinction coefficient and ranging probability.Furthermore,the formula of relationship between the atmospheric disturbance and attenuation and the ranging probability were obtained.Two measures that transmit multipulse to improve the detection probability and increase ranging pulse frequency to improve SNR were proposed.It provides the theoretical basis for improving the performance of laser rangefinder.
【Key words】 optoelectronics and laser; laser rangefinder; error analysis; detection probability; signal to noise ratio(SNR);
