处理双曝光数字全息的一种新方法
New method for processing double-exposed digital holography
摘要
Abstract
Analysing on the disadvantages of double-exposure holography,and using the flexibility of hologram recording and processing of digital hologrpahy,the difference digital hologram method (DDHM) for processing digital holograms of double-exposed digital holography(DEDH) was proposed.In the DDHM,the two digital holograms of object and deformed object are recorded,respectively,then subtraction of the two digital holograms is made and the difference digital hologram (DDH) is obtained.Finally the good quality interference fringes of optical waves of object and deformed object is got by virtually reconstructing the DDH.Comparing with DEDH and superposition digital hologram method(SDHM),the advantages of DDHM are,elimination of zero-order intensities of digital holograms is unnecessary,only the reconstuction of DDH is needed,and the quality of interference fringe is better.The principles of SDHM and DDHM for processing the digital holograms of DEDH were gived.The feasibility and superiority of DDHM were verified by experiments.关键词
