Product details:
The diffuse reflection laser speech information acquisition system is a new type of sound pickup equipment, which takes the invisible laser as the carrier signal, the target as the sensor, and the diffuse reflection laser signal modulated by the demodulated speech to realize the sound pickup.

System principle:
Invisible laser light is irradiated on the target, and the echo signal modulated by the voice is received and demodulated by the system, and the voice information is restored.
The longest distance of action is up to 450 meters. It can penetrate multi-layer glass. It has strong film penetration ability. The speech intelligibility is over 95%. It is small and portable. It has video and voice storage function.

Application scenario:
1.Vehicle environment   2.Field environment     3.Window environment   4.Indoor environment   5.Vision environment   6.Overlooking state  

System advantage:
1. role distance:as far as the biggesr range of up tp 450 meters.
2. objective universality:paper,metal,plastic,cloth, ceramics and other specific objectives;can penetrate laminated glass,has the strong ability of menbrane.
3. High voice intelligibility: over 90%
4. Small size, portable: integrated structure, high integration, good portability, simple operation, direct speech output
5. With video and voice storage functions: real-time synchronous acquisition of voice information and video information
6. High concealment, resistance to electromagnetic interference: no preset, the maneuverability is strong.
7.Wide application scenarios: such as car, building and field can be used
8.With independent intellectual property rights: no back door, high security.
