Paper Abstract

We discuss an approach to detect a 3D position or shape by reconstructing real images at multiple positions from a holographic fringe pattern produced on a charge-coupled device (CCD) camera. The calculation of the intensity distribution on a real image at a certain position can be performed by making the Fresnel transformation of the holographic fringe pattern. It is possible to detect the position of an object by comparing reconstructed images at multiple positions and by picking up one having peak intensity in them. In this paper, an approach to position detection using reconstructed images from a holographic fringe pattern and Fresnel transformation for image reconstruction are described. As experimental results, image reconstructions from holographic fringe patterns produced with one or two point light sources are shown. In conclusion, we discuss the accuracy of this method on z position.
