The invention relates to the field of telescope control systems, in particular to a telescope automatic control system based on a Kafka message bus. Traditional Socket communication is replaced by a Kafka message bus, the bottleneck of big data transmission among multiple subsystems is solved, a logic interlocking strategy is dynamically generated by an operation scheduling system based on the state of each subsystem, an observation task is automatically disassembled into cross-subsystem command flow arrangement, and the cross-subsystem command flow arrangement is distributed to a communication interface through an information interaction center. The solar telescope has the full-link automatic observation capability, subsystems are connected to a unified message bus through embedded Kafka middleware to form a publishing / subscribing communication mode, and seamless integration can be achieved only by defining an exclusive Topic when the subsystems are newly added or upgraded; the problem that the solar telescope is difficult to realize automatic observation due to insufficient data throughput of data interaction among subsystems in the existing solar telescope is solved.

The invention discloses an unsupervised reconstruction method for adaptive optical image restoration, which is applied to the technical field of astronomical observation and aims to solve the problem that in the prior art, the imaging resolution is reduced due to atmospheric turbulence in the observation of a ground-based solar telescope. According to the method, multi-frame blind deconvolution is creatively fused into an unsupervised deep learning framework, an encoder-decoder network is constructed to generate a potential clear image, meanwhile, a depth priori condition network is constructed to optimize a fuzzy kernel, and efficient recovery is achieved by solving network parameters and the multi-frame blind deconvolution problem through alternate iteration. A GCM model is introduced into a corrector to ensure stable convergence, and a BM3D algorithm is adopted in the denoising process. Compared with the prior art, the method does not need a large amount of training data, is high in generalization capability, is high in recovery quality, can process non-isoplanatic and multiband images, achieves the complementary advantages of a conventional algorithm and deep learning, is high in calculation efficiency, is high in practicality, and provides a more advanced and reliable image processing technology for the fields of astronomical observation and the like.

The application discloses a solar adaptive telescope, which comprises a primary mirror, a secondary mirror, a front mirror group, a wavefront corrector, a rear mirror group, a beam splitter, an observation system, a wavefront sensor and a wavefront controller. The wavefront corrector is placed in the pupil conjugate position of the folded light path of the telescope, so that the high integration of the solar telescope and the adaptive optical system is realized. Compared with the method of transforming the secondary mirror or the third mirror and the fourth mirror into a high-precision deformable secondary mirror, the original telescope main structure is not changed, and only the folded light path of the original telescope needs to be reasonably adjusted, so that the redesign and structural transformation of the support and thermal control system caused by the use of the complex deformable secondary mirror are avoided. The application has the advantages of wide application range, strong flexibility, simplified optical system structure, reduced number of optical elements and the like, and can effectively reduce the system inherent aberration and stray light and improve the solar energy utilization efficiency.

This invention discloses a device and method for detecting the water vapor composition and wind field occultation of planetary atmospheres, belonging to the field of planetary atmospheric detection technology. It includes a sealed mounting housing, a modular control unit, and an all-fiber optic unit. The device adopts a layered sealed structure of "upper-layer optics + lower-layer control." The optical unit receives sunlight passing through the planetary atmosphere via a solar telescope, mixes it with one laser beam split by a laser to generate a water vapor absorption spectrum, and extracts the peak wavelength λ'. Another laser beam passes through a built-in calibration gas cylinder to generate a standard absorption spectrum, and extracts the peak wavelength λ. Based on the Doppler frequency shift principle, the line-of-sight wind speed is inverted using the wavelength drift. This invention features strong adaptability to orbital environments, high integration, and high measurement accuracy. It can achieve synchronous in-situ detection of water vapor composition and wind speed in planetary atmospheric orbits, meeting the requirements of lightweight, radiation-resistant, and long-life interplanetary orbit detection, and is suitable for on-orbit occultation detection scenarios in planetary atmospheric orbits.
