中文摘要基于雅敏干涉装置,提出一种新的可变载频(条纹频率可调)的径向剪切干涉仪。该干涉仪主体由两块雅敏干涉平板、两对可旋转双光楔、两个可变比例的扩束镜组成;双光楔用于调节条纹周期,以获取最佳干涉图;两扩束镜的扩束比例可变,以调节最佳剪切量。两块平板加工误差一致,同时所有光楔来源于同一楔板,参数一致,两扩束镜的性能参数也完全相同,光路对称,严格等光程。提出的干涉仪可一次性完成非球面模具的测量;并根据被测面形情况进行条纹周期和剪切量的调节,获得了最佳条纹图。最后,对球面/非球面模具表面进行了测试。结果显示:通过调节双光楔和扩束比,此干涉仪可获得较好的条纹图,为多种非球面模具的进一步高效检测提供了新的思路。
英文摘要A new type of radial shearing interferometer with variable carrier frequencies (fringe frequency adjustable) was proposed based on Jamin interferometric plates. The interferometer mainly consists of two Jamin plates, two pairs of rotational optical wedges and two beam expanding/reducing systems with adjustable ratios. The rotational optical wedges were used to adjust fringe periods to obtain an optimum interferogram. The two beam expanding/reducing systems with adjustable ratios could achieve an optimum shear. Moreover, the two optical plates could be machined by cutting half to achieve the same machining error. All the optical wedges and beam expanding/reducing systems were the same in optical parameters and two optical paths were also symmetric and identical.The new interferometer could perform the measurement of aspheric lens mould at one time. The testing experiments of spherical and aspheric moulds show that the interferometer can achieve the best-quality fringe patterns and satisfactory shearing displacement at one time, which provides a solid foundation for the further measurement of various kinds of aspheric moulds.
