Embodiment Construction

[0017] The present invention will be further elaborated and illustrated below in conjunction with the accompanying drawings and embodiments.

[0018] figure 1 As shown, the Cassegrain type optical transmitting antenna widely used in space optical communication, because a large amount of energy of the laser Gaussian beam is collected on the central (optical) axis during the axial transmission process, the central part of the secondary mirror of the antenna is reflected to the circle of the primary mirror The energy in the hole will not be transmitted, and there will be a large central energy loss, so it will have a great impact on the energy transmission of the long-distance space optical communication system.

[0019] figure 2 with image 3 As shown, it is a ring laser source structure composed of a high-power line source LED ring array in the present invention. The light source selects high-power line source LEDs with a very small divergence angle in the slow axis directi...

Abstract

The invention belongs to the technical field of optical communication, in particular to a high-precision collimated optical antenna transmitting system capable of loading a radial radiation laser source. The design method of the antenna transmitting system is based on the three-dimensional vector reflection theorem, which is composed of an off-axis elliptical rotational surface secondary mirror and a confocal parabolic primary mirror. The radial radiation laser source used in the antenna emission system is a radial radiation linear laser source or a radial radiation ring laser source, which not only significantly improves the radiation power of the light source, but also reduces the difficulty of processing. The invention mainly solves the key technical problem of energy loss in the center of the secondary mirror in the traditional optical transmitting antenna, helps to improve the transmitting accuracy and transmission efficiency of the transmitting antenna in the optical communication system, and can achieve laser beam output without pre-collimation of the semiconductor laser output beam. High-precision collimated transmission of the beam close to the diffraction limit, and it is easy to realize the miniaturization of the optical communication transmission system.

Description

technical field [0001] The invention belongs to the technical field of optical communication, in particular to a high-precision collimated optical antenna transmitting system capable of loading a radial radiation laser source. Background technique [0002] The optical antenna system mainly expands the laser beam and further compresses the divergence angle. Optical antennas are key transmitting and receiving subsystems in the field of optical communication technology. High-precision collimation accuracy and high transmission efficiency are important guarantees for optical antenna systems to achieve long-distance transmission and high tracking accuracy. [0003] Space optical communication usually involves multi-wavelength transmission, and a reflective system (Cassegrain type) without chromatic aberration is widely used as the transmitting and receiving antenna, because a large amount of energy of the laser Gaussian beam is collected in the central (optical) axis during the a...
