相位差异技术在靶场光学测量设备中的应用

Application of Phase Diversity Technology in Range Optics Equipment

在分析光学设备需求、相位差异技术基本原理的基础上,对相位差异技术进行实验验证,并就其在靶场光学测量设备中的应用进行技术探讨。根据实验结果,原始图像的Fisher值为6.98×10-4,采用相位差异技术恢复后,图像的Fisher值提高到2.50×10-3,恢复结果验证了相位差异技术对水平传输过程中大气扰动的抑制能力。研究表明,该技术可有效改善大气湍流、光学系统像差对光学测量设备高分辨力成像的影响,还可应用于光学测量设备安装调试过程以及外场期间故障诊断和像差检测及校正。针对该技术实时性不足的问题,提出了优化算法、优化软件结构、选择高性能处理器等解决方案。

Following analysis of demands for range optics equipment and the principles and applications of phase diversity technology,this paper discusses the prospect of application of phase diversity technology in range optics equipment.The Fisher value of an original image of 6.98×10-4 is increased to 2.50×10-3 with phase diversity technology.Research shows the technology overcomes the impact of atmospheric turbulence and optical system aberration on high-resolution imaging.It can also be used in diagnosis and examination and correction of optical system aberration during assembly and field tests.The paper puts forward three ways to make up for the lack of real-time performance of the technology,i.e.,optimization of algorithm,streamlining of software structure and use of high-performance processors.
