Problems solved by technology

The collimator is used to calibrate, so that the communication light and the telescopic system are close to the same axis, so the error is large
In addition, its telephoto receiving system includes single parameters such as focal length, magnification, and depth of field. Such structural features cause that if the communication device chooses a telephoto receiving system, although the alignment accuracy is high, its field of view is narrow. It is not conducive to the initial capture of the target; if you choose a short-focus telephoto receiving system, although the field of view is large, its axial magnification is too small, and the alignment accuracy of the optical axis is low

Embodiment Construction

[0011] The specific implementation of the handheld dual-mode wireless laser communication optical transceiver targeting and receiving device of the present invention is as follows, as shown in the accompanying drawings.

[0012] There is respectively a set of aiming and receiving devices in the left and right lens barrels, and the aiming and receiving parts in each set of aiming and receiving devices share the same telescopic objective lens, connected by half-transparent and half-reflecting mirrors.

[0013] In a set of aiming receiving device, the coarse aiming part and the digital communication receiving part share the same coarse aiming telescopic objective lens. Coarse pointing half mirror 1 reflects digital communication light, the wavelength is one of 850nm, 1310nm, 1550nm, through the background light, that is visible light. The magnification of the coarse aiming part is 2 to 7 times, the field of view is 6 to 10 degrees, the diameter of the entrance pupil is 72mm, and ...

Abstract

The invention provides a hand-held double-mode wireless laser communication optical transceiver aiming reception apparatus, belonging to the wireless laser communication technology field. A present hand-held wireless laser communication device employs a single mode aiming receiving apparatus, an error is large, and contradiction of focal length and field of view exists. According to the invention, each of left and right lens barrels is provided with a set of aiming receiving apparatuses, an aiming part and a receiving part in each set of aiming receiving apparatuses share a same telescope object lens and are connected through a semitransparent mirror. In one set of aiming receiving apparatuses, a coarse sighting aiming part and a digital communication reception part share a same coarse sighting telescope object lens. A coarse sighting semitransparent mirror reflects digital communication light, backlight penetrates, magnification of the coarse sighting aiming part is 2 to 7 times, and an angle of visual field is 6 to 10 degrees. In the other set of aiming receiving apparatus, a fine sighting aiming part and an analog communication receiving part share a fine sighting telescope object lens, the fine sighting telescope object lens reflects most analog communication light, other analog communication light penetrates and is taken as beacon light, magnification of the fine sighting aiming part is 10 to 15 times, and an angle of visual field is 1 to 5 degrees.

Description

technical field [0001] The invention relates to a handheld dual-mode wireless laser communication optical transceiver aiming and receiving device. The aiming part includes two parts: coarse aiming and fine aiming, and the receiving part includes two parts: digital communication and analog communication. The lens barrel, which shares one lens barrel with fine aiming and analog communication, belongs to the technical field of wireless laser communication. Background technique [0002] Wireless laser communication refers to optical communication that uses laser waves as the carrier and the atmosphere as the transmission medium. Compared with microwave communication, wireless laser communication has the characteristics of large information capacity, wide frequency band, strong anti-electromagnetic interference ability, and good confidentiality. Compared with optical fiber communication and other wired communication, it has the advantages of flexibility, little impact on municip...
