一种激光雷达模块
本申请涉及激光雷达测量领域,尤其涉及一种激光雷达。
技术介绍
目前,公知的激光雷达由光源、接收装置、发射透镜、接收透镜组成光路系统。光源发出指定波长光束,接收装置接收返回的光束,通过TOF原理计算完成测距。现有雷达应用需求增多,对于不同量程、视场角的雷达需求日渐增加,单一参数的雷达很难满足多数场景的需求。但激光雷达的测量视场角、量程、光斑大小受光学透镜限制,现有技术光学透镜一般固定安装,无法拆卸,因此激光雷达应用范围受限。而如果更换透镜,透镜口径不一样,与其配套的固定装置需要重新设计、调整,通用性差。
技术实现思路
本申请在于提出一种激光雷达,通过将光学透镜与结构件组合在一起,组成发射、接收模组,更换不同参数的发射、接收模组,即可实现激光雷达的不同量程及不同视场角,满足各种不同场景的测试需求。本申请采用以下技术方案:一方面,一种激光雷达模块,包括发射光源、发射透镜、接收透镜、接收电路板,所述发射光源用于产生出射光束,出射光束经过发射透镜射向目标,目标返回的反射光经 ...
