The reconstruction methods of phaseinformation "Frozen" in an electron hologram are discussed.
讨论了“冻结”在电子全息图中的位相信息的再现方法。
2
Interpolation technique is used to solve the problem of phaseinformation missing generated by weak sequence signal.
相位插补技术主要用于解决因弱信号段而产生的相位信息缺失的问题。
3
Digital correlation method was used to extract phaseinformation as the phaseinformation of eddy current testing signals could reflect the characteristics of detecting system.
