脉冲激光测距仪灵敏度与消光比研究
RESEARGH ON THE SENSITIVITY AND EXTINCTION RATIO FOR PULSED LASER RANGE FINDERS
-
摘要: 本文直接采用模拟测距的消光比测试方法来检测脉冲激光测距仪的灵敏度,可以有效地排除远距离测距中气象差异的影响和地形条件的限制。通过对测试数据的分析并与测距能力相比较表明,本文提出的检测方法是有效的。Abstract: The extinction ratio test of analogue ranging is adopted directly to check the sensitivity of pulsed laser range finders, then the influence of weather and the limitation of terrain in long-distance ranging can be elinminated effectively. By analyzing the test data obtained and comparing them with the range measuring ability, it shows that this check method is effective.
