Dual-Magnification Technique for Reducing Moire Artifacts of Periodic Targets in Opto-Electric Imaging Systems

Zhang Haitao Zhao Dazun ( Color Science and Engineering L aboratory,Departmentof Optical Engineering, Beijing Institute of Technology,Beijing1 0 0 0 81 )  
In opto- electric systems,moire artifacts will occur when viewing periodic targets containing spatial frequencies exceeding half of the sampling frequency.The dual- magnification technique which can reduce moire artifactsby using two aliased frames produced in different sampling frequencies is proposed and discussed.Three computer simulation examples for qualitatively verifying the effects of the presentmoire artifacts reduction technique are presented.
