Embodiment Construction

[0029] The application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the related application, not to limit the application. It should also be noted that, for the convenience of description, only the parts related to the application are shown in the drawings.

[0030] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and embodiments.

[0031] It is understandable that when using lasers to eavesdrop on conversations in a room or in a car, if figure 1 As shown, it can be implemented by using a laser demodulator and a laser transmitter, and the laser emitted by the laser transmitter can be an infrared laser. A lase...

Abstract

The invention discloses intelligent glass, and the intelligent glass comprises a glass plate and an anti-eavesdropping film layer, wherein the anti-eavesdropping film layer is arranged on the glass plate, and the anti-eavesdropping film layer is used for receiving and absorbing eavesdropping electromagnetic waves and / or generating new electromagnetic waves after receiving the eavesdropping electromagnetic waves. According to the embodiment of the invention, the anti-eavesdropping film is arranged on the glass plate, so when eavesdropping electromagnetic waves are incident on the glass plate, the eavesdropping electromagnetic waves can be absorbed by the anti-eavesdropping film layer, and / or under the action of the eavesdropping electromagnetic waves, the new electromagnetic waves are generated and emitted out to cause damage to the eavesdropping information, so that the regulator cannot analyze the accurate eavesdropping information to cause an eavesdropping failure, thereby improvingthe anti-eavesdropping efficiency, and reducing the anti-eavesdropping configuration cost.

Description

technical field [0001] This application generally relates to the technical field of anti-eavesdropping, and specifically relates to a smart glass. Background technique [0002] Due to the directional and monochromatic properties of laser light, it is used in eavesdropping technology. A laser is used to generate laser light, which is emitted to the glass of the eavesdropped room or the window glass of a driving vehicle. When people in the room or in the car talk, the glass vibrates due to the sound changes in the room, making it reflected back from the glass. The laser contains the vibration information of the sound waves in the room. Furthermore, after being received by a laser outdoors, the sound signal can be demodulated to realize the monitoring of conversations in the room or in the car. [0003] At present, in order to prevent the content of the conversation in the room or the car from being eavesdropped, people in the room or the car use optical fibers when communica...
