摘要：

The performance of a digital speckle correlation interferometer using an image fibre is investigated theoretically and experimentally. An expression is derived for the visibility of correlation fringes in terms of spatial filtering properties of the image fibre. The visibility of fringes depends mainly on the resolution of the image fibre as well as the in-plane displacement of diffuse objects. The results show that a computerized video system combined with the image fibre is suitable for laser speckle interferometry.
