QT and Matlab multi-thread hybrid programming software architecture for adaptive optical control system

Abstract

The invention discloses a QT and Matlab multi-thread hybrid programming software architecture for a self-adaptive optical control system, which uses a cross-platform visual graphic development tool QTto build a multi-thread application program framework, and adopts a C/C + + language and a Matlab advanced scientific computing language to perform hybrid programming. According to the software architecture, the self-adaptive optical control system is divided into three function orthogonalized task modules including man-machine interaction, data communication and numerical calculation according to functional requirements, then a visual graph development tool QT is used for creating mutually independent working threads, and corresponding functions of the three modules are executed at the sametime in a parallel processing working mode. Meanwhile, a Matlab working engine is created in the numerical calculation module; an algorithm program realized by a Matlab advanced scientific computing language is directly called through a universal function interface provided by an engine; rich functions provided by Matlab commercial mathematical software are fully utilized for rapid calculation, the development difficulty of a complex algorithm of the control system is effectively reduced, and the development period of the control system software is greatly shortened.

Description

technical field [0001] The invention belongs to the fields of adaptive optics and computer software engineering, and in particular relates to a QT and Matlab multi-thread mixed programming software architecture for an adaptive optics control system. Background technique [0002] Since the 1950s, people proposed Adaptive Optics (AO), which effectively improved the imaging quality of the optical system, and has become an essential technology for astronomical ground-based telescopes to overcome the influence of atmospheric turbulence and obtain high-resolution imaging results (HW Babcock, The possibility of compensating astronomical seeing[J], Publ.Astron Soc.Pac., 1953, 65:229~236; Jiang Wenhan, adaptive optics technology[J], Nature Magazine, 2006:28(1):7 -13). The adaptive optics system is mainly composed of two parts: the optomechanical system and the electronic control system. The system mainly includes a high-speed signal real-time processor and control system software f...
