The visibility lidar adopts the design concept of dual telescope channels. The radar emits 1064nm laser, which is backscattered by aerosols and water vapor in the atmosphere. The laser is received by a telescope, a large telescope receives far-field signals, and a small telescope receives near-field signals. After data inversion calculation, zero blind spot detection can be achieved to obtain the distribution of atmospheric visibility.

·High energy, more adaptable to complex weather environments

·Dual mirror design for blind spot detection

·High spatiotemporal resolution ensures detection accuracy

·The whole machine is lightweight, ensuring fast installation and operation

·The whole machine has a high level of protection and can be used for outdoor observation
