AbstractIn order to improve the working efficiency of adaptive optical system researchers and meet the development needs of adaptive optics systems to woofer-tweeter multi-wave front correctors, a design method of adaptive optical system control software with convenient modification, full-functions and modularization was studied to adapt to the continuous updating and replacement of the laboratory equipment and avoid the problems caused by constantly updating and modification of the software during the experiment. In this paper the experimental software system requirements were analyzed from two aspects of function and performance, and a software architecture system of three layers was proposed: basic layer, functional layer and presentation layer. The shared memory and Critical Section Object were used to ensure the Real-time performance and accuracy of the adaptive optical system, and avoid the conflict and waste of resources. The Windows API Event was used to realize the synchronous coordination control of each thread. Based on the above ideas, a liquid crystal-deformation mirror multi-wave front correctors adaptive optical system control software was developed to test the feasibility, and the wave front information could be acquired and processed in 0.6 milliseconds. Finally, the adaptive optical correction was carried out with this software, the peak-valley value of wave front was reduced from 3.38 m to 0.95 m, and the root mean square of wave front was reduced from 0.66 m to 0.12 m with tip-tilt mirror and deformable mirror. The peak-valley value of wave front was 0.44 m; the root mean square of wave front was 0.02 m with tip-tilt mirror deformable mirror and liquid crystal corrector, the total delay time was 0.378 ms. The results show that the new control software can complete the woofer-tweeter wave front correction experiment with multi-wave front correctors, and at the same time, it has the advantages of convenient modification, complete function and modularization, it can meet the expected experimental requirements. 2018, Science Press.
