摘要
系统介绍了"神光-Ⅱ"装置上线成像速度干涉仪的研制情况。根据"神光-Ⅱ"靶场实际情况制定了光路排布方案,完成了成像系统的设计;根据物理需求、光路调节的难易情况、光学元件的加工难易度和加工成本等因素确定了干涉系统的结构,制定了干涉仪等光程调节方案,并获得了对比度较高的静态白光干涉条纹图像。通过调研和分析确定了任意反射速度干涉仪(VISAR)干涉图像的处理方法。
A detailed project for laser driven equation of state experiment is established.The project suits for active and passive diagnosing synchronously.The structure of the interferometer is designed by considering the physical requests,optical alignment,optical element processing and the conversion cost.High contrast white light interference fringes are obtained.An effective data analysis method(Fourier transform method) is selected by detailed research on the velocity interferometer system for any reflector(VISAR) interference fringe.
