| Abstract: | The basic concept and procedure of digital in-line holography are shown mainly for particle diameter measurement and the performance test results obtained in numerical simulations are demonstrated.Firstly,the simulation particles are randomly generated by computer with the Matlab software. Secondly,the diffraction pattern produced by the particles is directly recorded by computer.Finally,image reconstruction is carried out numerically on a computer using observed hologram patterns and particle diameter can be derived from the reconstructed images.The distinguishing method for focused particle is given. |
| Keywords: | particle diameter measurement digital reconstruction digital holography |
