Abstract

Using holographic techniques a Ronchi ruling with carrier may be generated which has the property of giving highly defined Ronchi fringes, instead of the diffraction-blurred fringes produced in the normal test. This procedure can be generalized to include the case of circular fringes.

摘要

利用全息技术可以产生带有载波的 Ronchi 光栅，它具有产生高清晰度 Ronchi 条纹的特性，而不是在常规测试中产生的衍射模糊条纹。该过程可以推广到包括圆形条纹的情况。
