Description

Technical Field

[0002] Acousto-optic modulation is an external modulation technology. The device that controls the intensity change of the laser beam is usually called a modulator. The modulation signal acts on the transducer in the form of an electrical signal, and then is converted into a wave field that changes in the form of an electrical signal. When the light wave passes through the medium, the optical carrier is modulated and becomes an intensity modulated wave that "carries" information.

[0003] For example, the Chinese authorized patent with announcement number CN220064547U (an acousto-optic modulator): including a shell, forming a receiving cavity, and opening two first mounting holes connected to the receiving cavity, wherein the two first mounting holes are respectively located on the two adjacent side walls of the shell; two collimators are respectively arranged on the shell through the two first mounting holes; an acousto-optic medium is arranged in the receiving cavity, and is used to modulate the optical signal incident from one collimator into the receiving cavity, and transmit the modulated optical signal to the other collimator for output. In this way, the present application can effectively reduce the length dimension of the acousto-optic modulator, and can improve the compactness of the spatial layout of the acousto-optic modulator, save space, and improve portability.

[0004] However, the position of the fixing seat of the existing acousto-optic modulator is fixed. During installation, it is easy to fail to install because the position of the mounting hole does not correspond to the fixing seat, and it is necessary to drill holes again, which is time-consuming and labor-intensive, inconvenient to install, and has poor flexibility. Therefore, it does not meet the existing needs. In this regard, we propose a modulator for visible light positioning. Utility Model Content
