In a recent Letter by Seo et al. [Opt. Lett.37, 4976 (2012)], the numerical correction of the quadratic phase distortion introduced by the microscope objective in digital holographic microscopy (DHM) has been presented. In this comment, we would like to draw to the attention of the authors and the readers in general that this approach could not be the optimal solution for maintaining the accuracy of the quantitative phase via DHM. We recall that the use of telecentric imaging systems in DHM simplifies the numerical processing of the phase images and produces more accurate measurements.
在 Seo 等人最近的一封信中[Opt. Lett.37, 4976 (2012)]，提出了在数字全息显微镜（DHM）中用数值方法校正显微镜物镜引入的二次相位失真。在这篇评论中，我们想提请作者和读者注意，这种方法可能不是通过 DHM 保持定量相位精度的最佳解决方案。我们回顾一下，在 DHM 中使用远心成像系统简化了相位图像的数值处理，并产生了更准确的测量结果。
