摘要
自从D.Post提出全息云纹干涉技术后,现已发展到各个方面,如断裂力学、复合材料力学、生物力学的性质测试上等均有应用。然而,对全息光栅、全息云纹技术在理论上发展存在欠缺。本文用傅里叶光学理论推导全息光栅的栅频、全息云纹的位移公式,进一步完善了全息云纹技术的理论,为全息云纹技术广泛应用提供了理论依据。
Since D. Post promoted the holographic moire' interferometric
techniques. It has been developed in all kinds of aspects. It is applied in measuring mechanical parameters in the fields of fracture mechanics, composite material mechanics, biomcchanics etc. Howerver, some problems in the development of the holographic grating and holographic moire' techniques theory are still existed. This paper deducted the frequency of holographic grating and the equation of moire/ method's displacement with Fourier opticsal, and improved the holographic moire' technologic theory. It provides a theoretic foundation for extensive applying of the holographic moire' techniques.
