Product Description

 

Product Description
The system adopts innovative achievements such as self-development dual optical path laser technology, matrix detection technology and digital focusing technology. Taking ultra long distance, no preset and non-contact as the application environment, the system can realize the synchronous pickup of target sound information hundreds of meters away, and can effectively meet the acquisition needs of relevant departments for target sound information. It is an important means of sound information acquisition.
The system has obvious advantage in sub nano weak vibration measurement and weak return light detection ability, and has outstanding performance in target medium adaptability,  working distance, window permeability and so on.
The system is highly integrated, easy to operate, easy to carry and fast to deploy.
