Problems solved by technology
[0003] On the road of integration, it is inevitable to encounter some technical problems: small-volume detection front-end is highly integrated, requiring integrated design of laser emission optical shaping and drive; traditional double Gauss lens, anti-telephoto lens and other imaging lens group structures cannot be taken into account Optical design with large aperture and short focal length; after the integrated miniaturization of transceivers, large anti-electromagnetic interference measures such as electromagnetic shielding covers and transformers are no longer applicable; the distance between transmitting and receiving is closer, and the ability to resist external environmental interference becomes weaker
