分析了非远心成像系统在定量相位数字全息显微术中引入的误差。计算机模拟的实验结果表明，即使是可以忽略的误差的半径和曲率中心的数值补偿需要摆脱剩余的二次相位因子引入误差的相位测量，这些误差取决于在视场中的对象的位置。然而，当远心成像系统用于记录的全息图，数值模拟和实验结果表明，位移不变的行为的定量相位数字全息显微镜。(C)2013年美国光学学会
Inaccuracies introduced in quantitative phase digital holographic microscopy by the use of nontelecentric imaging systems are analyzed. Computer modeling of the experimental result shows that even negligible errors in the radius and center of curvature of the numerical compensation needed to get rid of the remaining quadratic phase factor introduce errors in the phase measurements; these errors depend on the position of the object in the field-of-view. However, when a telecentric imaging system is utilized for the recording of the holograms, the numerical modeling and experimental results show the shift-invariant behavior of the quantitative-phase digital holographic microscope.
