| Abstract: | The diffraction patterns produced by the particles are directly recorded by a conventional CCD camera.In digital holography,image reconstruction is carried out numerically on a computer by using observed hologram patterns and some quantitative information can be derived from the reconstructed images.The basic concept and procedure of digital in-line holography are shown mainly for particle location measurement and the performance test results obtained in numerical simulations and experiments are demonstrated to examine the potential of the present method. |
