【摘要】 目前的单光子激光测距系统,在作用距离和测距精度方面拥有较大优势,但探测景深相对较小,严重限制了系统的应用范围。分析了单光子测距系统景深受限的原因,提出采用多探测器协同工作的方式来提高系统探测景深的方法。相比现有的单光子测距系统,其探测景深可以得到有效提高,具有明显的优势。更多还原

【Abstract】 The depth of detection is of great importance to laser radar systems.The larger the depth of detection,the more information can be acquired during detection,especially in the case of moving target acquiring and searching.Single Photon ranging is under development for its long detection range,precise ranging accuracy.But due to the noise performance of such systems,the depth of detection is short compared to other kinds of laser radar systems,which makes it less preferable for some kinds of applications.A novel method of utilizing 2 detectors to overcome this shortage was developed,which can improve the depth of detection several times better than the current systems.更多还原
