脈沖激光測距儀靈敏度與消光比研究
RESEARGH ON THE SENSITIVITY AND EXTINCTION RATIO FOR PULSED LASER RANGE FINDERS
-
摘要: 本文直接采用模擬測距的消光比測試方法來檢測脈沖激光測距儀的靈敏度,可以有效地排除遠(yuǎn)距離測距中氣象差異的影響和地形條件的限制。通過對測試數(shù)據(jù)的分析并與測距能力相比較表明,本文提出的檢測方法是有效的。

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. -
