Reconstruction of Multilayer Samples by In-line Compressive Holography
摘要
Abstract
In order to study the reconstruction effect of three-layer samples using compressive holography,tomography experiment is proposed and compressive holography and traditional back-propagation digital holography is analyzed.The frequency domain sample reduction to make hologram sparse is used,remaining 25％ data of the original hologram.Through the simulation experiment,that the correlation coefficient of the reconstructed image by compressive holography and simulation sample can reach 0.64.4f optical system is introduced,and it separates three-layer samples apart with compressive holography method which can make reconstructed images much clearer and suppress background noise.关键词
