摘要
本文研究了透射式能见距离激光测量仪的测量精度及其受后向散射能的影响 ,导出了能见距离的测量误差、能见距离、仪器与合作目标间的距离三者之间的关系。分别讨论了当仪器与合作目标间的距离确定时 ,在不同的能见距离下以及当能见距离确定时 ,在不同的仪器与合作目标间的距离下能见距离的测量精度及其受后向散射能的影响 。
Measurement accuracy of visibility and effect by back-scattering energy in transmission detection instrument for visual range are studied.The relationship among standard measurement error and relative measurement error of visual range,laser energy received by the instrument and the distance from the instrument to cooperation target is gained.The measurement accuracy of visibility and effects by back-scattering energy at fixed distance from the instrument to cooperation target but different visual range,and at fixed visual range but different distance from the instrument to cooperation target are discussed.The effects on measurement accuracy of visibility by choice of receiving lens diameter are analyzed.A series of reasonable conclusions are obtained.
