Abstract

The invention relates to an underwater optical communication automatic aiming, capturing and tracking device. The underwater optical communication automatic aiming, capturing and tracking device comprises a transmission device and a receiving device, wherein the transmission device is arranged on a manned submersible, and the receiving device is fixedly arranged on a seabed sensor; the transmission device comprises a biaxial universal stage, an image detector, a laser transmitter, a digital image micro-processor and a movement control single chip microcomputer; the biaxial universal stage is used for completing the pitch and deflection rotating of the image detector and the laser transmitter through a stepping motor I, a stepping motor II, a high-precision rotary stage I, a high-precisionrotary stage II, a pitch U-shaped bracket and a yaw U-shaped bracket; the receiving device comprises a light-operated switch, a power source and a receiving response light source which are serially connected, the light receiving surface of the light-operated switch is positioned at the focal point of a convergent lens, and a circuit is engaged when the light receiving surface of the light-operatedswitch is radiated by laser; a beam expander is positioned just in front of the receiving response light source. The underwater optical communication automatic aiming, capturing and tracking device has the advantages that the aligning speed and precision of the receiving end and transmitting end can be guaranteed, and the smoothness of an optical communication link is maintained when the submersible is slightly disturbed by microwaves.

Description

technical field [0001] The invention belongs to an aiming, capturing and tracking device, in particular to an underwater optical communication automatic targeting, capturing and tracking device. Background technique [0002] Existing automatic aiming, acquisition and tracking systems are mostly used in air-to-ground communications and satellite communications, and are generally not used in underwater communications. At present, acoustic communication is generally used underwater, and the speed of optical communication is better than that of acoustic communication. Underwater optical communication has many advantages: strong penetrating ability, high operating frequency, wide communication frequency, strong data transmission capability, concealed and safe beam, and small size and weight of equipment, so it has a wide range of applications in submarine communication, ocean detection, etc. prospect. If optical communication is applied underwater, the alignment of the two ends...
