Abstract

The invention discloses a preprocessing system for adaptive optics. The system comprises an interface module, a processing module, a simulation module and a bus module. The system is used for the off-machine data processing of adaptive optics. The system can be connected with an optical wave front detector, a laser guide star system, a deformable mirror system and a simulation system for auxiliary test in off-machine state, and can be connected with an on-machine through an optical fiber bus so as to transfer data and commands. According to the system, the problems of multiple external systems, low intelligence and difficult updating and upgrading in wave-front processing of existing adaptive optical systems are solved, and the interface forms and software protocols of the external systems are simplified and standardized. The system particularly can be applied to adaptive optical systems under multi-laser guide star systems, multi-Hardman wave-front detectors and multi-deformable mirror systems.

Description

technical field [0001] The invention relates to the technical field of adaptive optics, in particular to a preprocessing system for adaptive optics. Background technique [0002] Adaptive optics technology is widely used in astronomical observations, and ground-based telescopes are developing towards large-scale development. At present, most of the ground-based telescopes under research in the world have a diameter of more than 30 meters, of which the EURO50 project has a diameter of 50 meters, and the OWL project has a diameter of 100 meters. Optics has proposed technologies such as multi-point laser guide star, multi-point adaptive multi-objectAO (MOAO), and layered conjugate adaptive multi-conjugateAO (MCAO). As technology advances require multiple deformable mirrors, multiple laser guide stars or multiple wavefront detectors to work together, a single computing processing system has been unable to complete the collaborative work of multiple deformable mirrors, multiple l...
