Examples
- Based on the psf , some basic characters including reconstructed image lateral resolution and the size limit of the recorded object in the in - line phase - shifting digital holography are theoretically discussed
第四章讨论了同轴相移数字全息中，相移角的选取、相移误差以及量化误差对再现像的影响。 - Chapter 4 : the influence of different phase - shifting angle of reference wave in recording , of the phase - shifting error and of the quantization error on the quality of the reconstructed image is investigated respectively in two - step phase - shifting inline digital holography . and an effective method of eliminating the phase - shifting error is presented , in which the summation of the intensity bit errors of the reconstructed image is taken as an evaluation function for an iterative algorithm to find the exact phase - shifting value . the feasibility of this method is demonstrated by computer simulation
通过数值分析不同相移角的选取对再现像的强度误差的影响，发现再现像强度误差依赖于记录时相移角的选取，当相移角在一定范围内，其再现像的强度误差相对较小；提出了一种有效消除相移误差的新方法，并将其应用于二步同轴相移数字全息，对此进行了计算机模拟，得到了很好的结果，证明该方法对于相移误差的消除是很有效的；对量化误差所作的数值模拟发现，当信号被量化成8比特（ bit ） ，即256个灰度级以上，量化噪声的影响相对较小。 - The philosophy and methodology of performance - based seismic design ( pbsd ) has been an extensive topic discussed by earthquake engineering experts at home and abroad . in this paper , research work on displacement - based seismic design ( dbsd ) at home and abroad are systematically collected and analyzed . based on the available references of seismic behavior of frame - wall buildings , the method of dbsd of reinforced concrete frame - wall buildings is primarily put forward by taking into account the fault of methods of seismic design in current code . the main contents are as follows : the actual stiffness of frames and seismic walls at different deformation stages are determined from experimental data , and the results are adopted in the dbsd method
