Double-source holographic contouring using fibre optics

In this paper holographic contouring by the movement of the object beam through fibre optics is described. The contouring fringes can be visualized on the object surfaces. This contouring technique is based on a double-exposure hologram through fibre optics. Single-mode fibres are used to transfer b...

Description
Summary:In this paper holographic contouring by the movement of the object beam through fibre optics is described. The contouring fringes can be visualized on the object surfaces. This contouring technique is based on a double-exposure hologram through fibre optics. Single-mode fibres are used to transfer both object and reference beams. Between the two exposures the object illumination fibre is displaced. The fringe type is analysed and several experimental results are given.
