| Abstract: | A new autofocusing method for particles located in different plane in particle field detection with digital in-line holography is proposed and experimentally verified by analyzing the characters of recording and reconstructing about digital in line holography.The focus measure function and the operation procedure of particle segmentation identification and independent focusing are presented.The proposed method is verified through the experiments of one layer of one particle,two layers of two particles and multi-layers of multi-particles. |
| Keywords: | Digital in-line holography Particles field detection Focus measure function Particles segmentation and identification Independent focusing |
